Mh. Osterhout et al., RECENT ADVANCES IN THE CYCLOADDITION CHEMISTRY OF ISOMUNCHNONES AND THIOISOMUNCHNONES, AN UNDER-UTILIZED CLASS OF MESOIONIC COMPOUNDS, Synthesis, (2), 1994, pp. 123-141
This review describes the methods of preparation and use of isomunchno
nes and thioisomunchnones to synthesize furans, 2-pyridones, functiona
lized lactams and other heterocyclic ring systems. Some promising intr
amolecular dipolar cycloadditions of these mesoionic compounds, and th
eir potential for natural product syntheses, are presented.
