Abstract

N-α,β-Unsaturated acylanilides, which contain various heterocyclic rings in their acyl groups, i.e., α-pyrone, α-fnranone, α- and β-furans, and an ortho-substituent on the benzene ring, were found to undergo photocyclization to afford various products depending upon a heterocycle, and an ortho-substituent which brought about smooth photocyclization.
