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.
