Heterocyclic Rings

heterocyclic rings in easy way what is the heteroatom let us take one example of the ring like this and is the well-known ring that is the benzene now this benzene is made up of carbon and hydrogen but if you take another ring like this and here you can observe a nitro cell so what is this nitro some nitrogen can be called as hetero atom so any atoms other than this carbon and hydrogen can be called as hetero atoms now this ring is the one of a heterocyclic ring having a nitrogen as in hetero atom and this is called as pyridine similarly understructure is here you can observe two hetero atoms this is one hetero atom and is endre hetero atom and this is nothing but pyrimidine in this way we can write so many types of heterocyclic rings but how we can remember these heterocyclic rings if you carefully observe both of these rings are having the same prefix pi and there hang the same suffix ein so we can remember the heterocyclic rings by using few of the prefixes and by using few of the suffixes so in this video we will go with the heterocyclic rings how we can remember and and any possible suffixes as well as the prefixes present for the heterocyclic rings suffix for the heterocyclic rings so we can have a a broad heterocyclic norman cliche but here we are going to see how easily we can remember this heterocyclic rings by using fear of the suffixes the suffix for the hetero cycler rings can be given based on the ring size what is the ring size and what is the suffix if it is unsaturated and if it is saturated but here we have shown the suffixes for the saturated rings which are hanging the nitrogen so if your ring size is 3 and if it is unsaturated that is the Eirene and if it is saturated and nitrogen containing ring it is the I reading similarly for that is eat and saturated eating 5 vole and if it is saturated ho leading and 6 ein but there is no suffix for the generator ring from the ring size 6 onwards the saturated rings will not have any a particular suffix similarly the ring size 7 the suffix if it is unsaturated a pine but there is no suffix for the saturated similarly 8009 owning and 10 is in so if we remember these suffixes we can easily build what is the name of the heterocyclic ring system and another important thing is the replacement norm treasure that we use along with the heterocyclic rings for example if for nitrogen is there nitrogen is actually replacing the carbon of the aliphatic ring so here we can use a few other terms based on the hetero atom so if nitrogen is there we can use the prefix Asia if oxygen is there Aqsa sulfa is there tiya and phosphorus as phosphor so in this way any of the hetero atom can be indicated by few of the prefixes so by using these suffix and prefix now let us go with the discussion of how easily we can remember the heterocyclic ring systems so let us start with the first one three membered ring so there's simple three membered ring containing the nitrogen has the hetero atom so what is the name of this ring system because the nitrogen is present we have to use the prefix aza press because it is in three membered unsaturated ring systems so the suffix is the Eirene so as ax plus irene so this is nothing but the AG ring so nitrogen containing heterocyclic ring system which is unsaturated is the AG ring similarly if it is saturated so again in the prefixes as ax plus whenever it is saturated we can use the suffix e reading so plus e reading so as R plus irid in that is the AG reading is reading is one of the ring system present in few of the drugs like the Toyota Toyota is one of an anti-cancer agent which is hang the AG reading ring system similarly another example is the three membered heterocyclic ring with augs and as the header atom so now here we have to use the prefix Aqsa plus again the irene so odds are press it is the ogz earring similarly if it is saturated then what happens in the previous example we have seen that the suffix is reading if it is saturated but that is a suitable for the nitrogen-containing ring systems but this ring is not having the nitrogen they sang the oxygen when the ring is having hetero atoms other than the nitrogen we should use a different suffix so if other than the nitrogen is there then if it is saturated we have to use the simple suffix as in en indicates like alkanes they are saturated now this ring system is hogs r+ in the Irene we had replaced the ion you with the end so hogs are plus I rain so here n indicates it is saturated so hogs are plus I rain that is oxy rain oxygen is the three membered ring system containing oxen and completely saturated similarly with the sulfur the sulfur can be indicated by taya plus it's a three membered ring system and unsaturated so that is Irene so that is taya press Irene tae Irene similarly this ring system here taya plus if it is saturated we can write the Irene plus in there is a I rain so taya plus I rain so that is a tie I rain now let us go with the four membered ring systems so this is the four membered ring system again containing the nitrogen and we here we are going to discuss a few have the heterocyclic ring systems which are more existing in the nature or synthetically so this is the one of the ring system so here what is the name again we have to use the asia and because it is a four membered ring system which is saturated we have to use the eat it in so as a plus 18 that is the age it in similarly under four membered ring system with aux-in so here we have to use the Aqsa so here eat is the suffix for the unsaturated ring system but because it is saturated and now the it becomes e 10 so ox r plus e 10 that is a hogs attain and actually the five membered ring systems so this is the one of the five membered ring system containing the nitrogen and this is an the hydro cycling system having onsen and this is another heterocyclic ring system with the sulfur now what are the names for these three ring systems here the first one is the PI role so here PI R is the one of the 10 we are going to use in many of these heterocyclic ring systems and wall is the suffix for a five membered ring system so that is a fireplace wall PI role but for second one the name is the few ROM here we are not using any suffix like the wall even it is a five membered ring system that means this ring is having an exception and it is commonly known as fewer on before developing this nomenclature it is well known as a few on so the name is going to be retain as fewer on similarly third one is the thiophene so these ring systems are hanging at different names like the PI Rolfe your an anti often even all these are belonging to the five member ring systems but based on these names we can write the names of their higher heterocyclic ring systems now this is an another example of the five membered ring system containing the nitrogen and it is saturated and similarly in the ring system is having a five membered ring system with oxen and saturated so what are the names for these ring systems for the first one it is a saturated form of the PI role so here we can use the suffix like the holiday in Volodin indicates a five-member ring system which is saturated so PI R + volodine that is the pyro leading so pyro linen is a saturated five membered ring system containing nitrogen similarly for the second ring which is a saturated form of the firaon there is no specific prefix and suffix but simply we can represent it as tetrahydrofuran commonly known as THF tetrahydrofuran is the saturated form of the Fuhr on in this way for few of the hetero cycle living systems the common name is well distributed next one is the five membered ring systems with two hetero atoms so this is one example of the five membered ring system with two nitrogen's as the hetero atoms and now what is the name of this heterocyclic ring so if we compare this ring system with the pyro what is the difference pyro Lee sang-woo only one nitrogen and this is having the two nitrogen's so this can be written as PI roll is having an extra nitrogen which can be indicated by aza so which can be incorporated in between the name so we can write like Pyrus as a plus or so PI R indicates one of the nitrogen and as I indicates and the nitrogen and wole indicate is a five membered ring system so now this is the payaso so pi Rizal is the nitrogen containing five membered ring system with the nitrogen's at the first and second positions and this is an the ring system and here what is the name of this ring system so this ring system can be written as e mid plus HR plus or so here amid again indicates a nitrogen containing ring and as I say extra nitrogen and all is a five membered ring system so this is the imidazole how can you remember this PI Rizal and imidazole we may be confused with that PI R is really saying the nitrogen's at the first and second position or first and third position it can be easily remembered that this image indicates here where letter M is there M indicates like the meta portion that means the third position just like the aromatic ring systems or the meta para so in the M indicates here the meta position that means the second nitrogen is present at the meta portion to the first one that is a third position so whenever M is there then indicates the third position so emitter Jolie's hang the X second nitrogen at the third position in this way we can easily differentiate the PI rizal and emerge all pyroar is one two imidazole is one three similarly in the ring system is having oxygen nitrogen what is this so here the oxygen is present to the first position and nitrogen is present at the second position always we have to give the preference to the aux-in then to the nitrogen so here the augs and nitro is not present at the first and second position and oxygen can be indicated by Aqsa and nitrogen as aza and it is a five membered ring system all so this is in oxygen the hetero atoms are present at the first and second position so this can be written as 1 2 auxes or so this one - ox all is commonly known as ice axes all so here you have to remember that i Sox's all the iso indicates first and second position if we see an the relator ring like this now here oxen is present at the first question whereas nitrogen is present at the third position so this is again Aqsa plus a surplus wolf with the first and third questions having augs in a nitrogen so this is the one three axes all so this one 3 ox all is commonly known as oxes all so oxygen is the ring where hetero atoms are present at the first and third position but in the ice ox soul they are at the first and second position similarly with the sulfur again we can write the prefix for the sulfur as the thigh ax plus as ax plus all so this is the tie a Joel and if we indicate the positions this is the one two ties all similarly this is the nothing but ties all with the first and third portion so this is the one three ties own just like the Ox is all here the first ring you can be called as I so thighs or and second ring can be commonly called as simply thighs own so thigh Joel indicates first and third portion I so thighs all indicates first and second positions and again here sulfur should be given more reference than the nitrogen next one is the five membered rings with three hetero atoms so let us take one example here the sulfur nitrogen and nitrogen so sulfur is at the first position and n the night wasn't at the second portion and third nitrogen is at the fifth position so here the hetero atoms are present at the first second and fifth positions and the prefix is the thigh ax and here two nitrogen's are there therefore it is die as ax and it is a five-member ring system that is all so this that tired is all but whatever the numbering is 1 2 5 so 1 2 5 tired is all this is a again in the ring system now here the sulfur is at the first position whereas the nitrogen's are at the third and fourth positions so this is again the theorized ol but it is 1 3 fourth iodized all [Music]
