Synthesis and Characterization of Fused Rings from Mannich Bases.

Abstract

In this work , four new compounds of mannich bases were synthesized through reaction of diketone compounds with ammonia or amine derivatives to give enamino ketone as intermediate , which reacts with aldehyde compounds to yield compounds [1-4] . The structures of all synthesized compounds were characterized by (C.H.N)elementary analysis , 1HNMR spectra and FT-IR spectra.The data obtained gave good support for synthesized compounds [1-4] .
