Reaction Steps
The title compound II-ao was prepared in 70% yield from 3,3:17,17-bis(ethylendioxy)-6-(E)-methoxyiminoandrostane by the procedure described above for the preparation of 6-methyleneandrostane-3,17-dione (II-ac, Prepn. 13). The combined organic extracts were washed with H2O, dried over Na2SO4 and evaporated to dryness. 1H-NMR (300 MHz, acetone-d6, ppm from TMS): δ 3.78 (3H, s), 3.37 (1H, dd), 2.68-1.14 (19H, m), 1.01 (3H, s), 0.98 (3H, s).
