Microwave-Assisted Synthesis: Fused Five-Membered<i>N</i>-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 fused five-membered heterocyclic compounds synthesis is presented, focusing on the developments in the past 5–10 years. This contribution covers the literature concerning the total synthesis of fused N-heterocycles.
