Abstract

Thermal rearrangement of 2H-azirines having a cyclopropane ring was revealed to give pyridines. Ene reaction involving a C=N bond to form tricyclic compound was observed in the case of 2-cyclopropyl-2H-azirine having an isobutenyl group cis to the azirine ring, whereas the trans isomer gave a pyridine ring exclusively.
