N2 - The irradiation of 17β‐acetoxy‐4‐oxa‐1,5‐androstadien‐3‐one (12) yielded the two stereoisomeric spiro‐lactones 13 and 14, which result from a di‐π‐methane photorearrangement. A third product, the oxa‐anthrasteroid 15, was also isolated (Scheme 3). Copyright © 1978 Verlag GmbH & Co. KGaA, Weinheim
