Have you heard of an internet search engine or perhaps a library?
Yes, I heard of an internet search engine . ut if I am asking for something here it means that I am unable to get it anywhere else and that's why I am asking for help.
Secondly , if you haven't read my question properly the please read it again. I am asking about
good sites and not books. I know a book is a very good place to find something, but i am unable to search through them at this very moment, so didn't asked for them. ut if want to tell about some good books then please go ahead.This information will be of great use for me as well as others.
What kind of level do you need to know? Are you an undergraduate, postgraduate, pharmaceutical industry etc...
I am sorry. I agree that this was my mistake.
I need to know about synthesis and reactions of heterocyclic compounds 3,4,5 and 6 membered rings with 1 or more hetero atoms.
In 3-membered : Azirine, Aziridine
In 4-membered : Azetidine
In 5-membered : Pyrrole, furan, thiophene

and many more
