✦ Synopsis

Abstract

The irradiation of the title compound 6 with UV. light and under photosensitized oxidation conditions yields products which are characteristic of the photo‐oxidation of the enamide moiety of 6. In contrast to the situation encountered in the case of the irradiation of its carbocyclic and 4‐oxa analogues 1 and 2, respectively, no compound resulting from a di‐π‐methane rearrangement of the Δ^1,5(6)^‐unsaturated system of 6 has been so far detected.

## Abstract The photo‐oxidation of the title compound (**1**) is described. The isolated products are the result of a [2 + 2] oxygen addition to the olefinic double bond of the enamide.
