Synthesis of (5,6,7,8)-Membered Rings of (Sulfur ,Nitrogen) via Cyclization of Imine Compounds

Abstract

In this paper , synthesis of a series of compounds from  hetero (Atoms, cycles) like  (5,6,7,8-membered )ring via cyclo addition reaction of anil compound to produce compound [1-13], this reactions involved addition of  carbonyl compounds like (( succinic acid , malonic acid , any compounds have  two terminal  from  amine  and  thiol or  carboxyl group)) to anil compounds  to  produce  various  membered  rings. The structure of the newly synthesized compounds [1-13] were confirmed with (C.H.N)- analysis & substantiated with (FT.IR ,H.NMR) data  & melting points.

Keywords : eight membered , sulphur ,macrocycle , Imine ,heterocycle, five membered.
