Glycine catalyzed convenient synthesis of 2-amino-4H-chromenes in aqueous medium under sonic condition.

Bandita Datta1, M A Pasha.   

Abstract

A one-pot three-component condensation of an aldehyde, malononitrile, and resorcinol has been achieved by ultrasound method. The reaction has been catalyzed by glycine in aqueous medium. This protocol afforded corresponding 2-amino-4H-chromenes in shorter reaction times, high yields and simple work-up procedures with the green aspects by avoiding toxic reagents. Copyright Â
