Participants

Reaction Steps

The 3,3:17,17-Bis(ethylendioxy)-7-methyleneandrostane was prepared in 85% yield from 3,3:17,17-bis(ethylendioxy)androstane-7-one by the procedure described above for the preparation of 3,3:17,17-bis(ethylendioxy)-6-methyleneandrostane (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 4.67 (1H, m), 4.60 (1H, m), 3.86 (8H, m), 2.20-1.10 (20H, m), 0.97 (3H, s), 0.86 (3H, s).
