Abstract

Intramolecular photocycloaddition reaction of dihyro-4-pyrones to alkenes (1), followed by fragmentation then subsequent aromatic annelation, carried out by two alternative methods, has been performed efficiently. The sequence provides a convenient method for the construction of substituted phenols fused to aliphatic ring (4).
