Notes:
Irradiation at 254 nm of 19-dimethoxyandrost-4-en-17 β-ol-3-one acetate (8) afforded the epimeric cyclization products 9 (yield 20%) and 10 (4%). Similar transformations were also achieved with the analogous dimethoxy-enone 24 (→ 25, 65%), and-dienone 30 (→ 31, 72%), and with the methoxy-enone 33 (→ 34, 30%), and-dienone 35 (→ 36, 17%).
