Synthesis of 2H-Chromenes,Enones,Chalcones and biological studies

Synthesis and Biological studies of 2H-Chromene derivatives, Enones and Chalcones have been divided into two chapter. Chapter-I describes the Synthesis of new (E)-4-(2-phenyl-2H-chromen-3-yl)but-3-en-2-ones. 2H-Chromene aldehydes were synthesized by Michael-Aldol Reaction. Further Aldol reaction provided alpha, beta unsaturated ketone.In vitro antimicrobial activities of the synthesized compounds were evaluated. Chapter-II elaborates synthesis of enones and chalcones and their Biological activities
