Abstract

Abstract: A variety of _-acetamido ketones and ketoesters are readily prepared in high yields under extremelymild conditions via a three component coupling of aromatic aldehydes, enolizable ketones or _-ketoesters andnitriles in the presence of 10 mol% of ferrous sulphate  and a stoichiometric amount of acetylchloride. A solution of 10 mol% of ferrous sulphate  in acetonitrile provides a convenient reaction medium to carry out athree component reaction under mild conditions with high yield .Synthesized compounds are studied for their microbial activity.
