Photochemical Behaviour of 17β‐Acetoxy‐4‐aza‐1,5‐androstadien‐3‐one: Photo‐oxidation vs. Di‐π‐methane Rearrangement

Abstract

SummaryThe 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-n-methane rearrangement of the A 1.5(6)-unsaturated system of 6 has been so far detected.
