Polycyclic Six-Membered N-Heterocycles: Microwave-Assisted Synthesis

The development of new strategies for synthesis of polycyclic heterocycles has remained a highly attractive but challenging proposition. An overview of the application of microwave irradiation in nitrogen-containing six-membered polycyclic 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 N-heterocycles.
