Recent Impact of Microwave-Assisted Synthesis on Benzo Derivatives of Five-Membered N-Heterocycles

Abstract

The development of new strategies for the synthesis of small-sized heterocycles has remained a highly attractive but challenging proposition. An overview of the application of microwave irradiation in nitrogen-containing benzo derivatives of five-membered heterocyclic compounds synthesis is presented here, focusing on the developments in the past 5–10 years. This contribution covers the literature concerning the total synthesis of benzo derivatives of five-membered N-heterocycles.
