An Efficient One-Pot Procedure for Preparation of 2,4(1H,3H)-Quinazolinediones and 2-Thioxoquinazolinone Derivatives Under Microwave Irradiation

Abstract

An efficient one-pot synthesis of 2,4(1H,3H)-quinazolinediones and 2-thioxoquinazolinone derivatives are given by the condensation of isatoic anhydride, primary amine and urea or thiourea in the absence of organic or inorganic reagents under microwave irradiation.
