Abstract

Chalcones (3a-3d) were synthesized by two routes conventional and microwave assisted synthesis methods. Claisen-Schmidt reaction (route A) entails base catalyzed cross-aldol condensation of appropriate aldehydes. Microwave aided synthesis (Route B) resulted in a significant increase in reaction rate, as well as higher yields. This method provides a simple, clean, quick, efficient, and cost-effective way to synthesize a large number of organic compounds. The compounds have been screened for they possess a broad spectrum of antibacterial activities.
