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

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
