One-Pot Greener Protocol for the Synthesis of Substituted Coumarins

Abstract

An expeditious one-pot procedure for the synthesis of substituted coumarins under microwave irradiation is accounted. The method describes an easy and fast method for the synthesis of substituted acetoxy coumarins which are very good fluorophores for medical as well as industrial applications. It makes use of easily available reagents such as triethylamine and acetic anhydride as catalyst. The method finds good applications for the synthesis of multisubstituted coumarins.
