Microwave Assisted Facile One - Pot Synthesis of Substituted Isatoic Anhydrides from Corresponding Carboxylic Acid Anhydrides

Abstract

An efficient microwave assisted protocol for the exclusive one-pot synthesis of isatoic anhydrides (3, 5a-c, 7 and 9) by the heterocyclisation of carboxylic anhydrides (1, 4a-c, 6 and 8) with trimethylsilyl azide (2) is described.
