实验过程

7α-Hydroxymethylandrostane-3,17-dione II-av was prepared in 85% yield from 3,3:17,17-bis(ethylendioxy)-7α-hydroxymethyl-androstane by the procedure described above for the preparation of 6-methyleneandrostane-3,17-dione (I-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 3.71 (2H, m), 3.30 (1H, t), 2.50-1.25 (21H, m), 1.12 (3H, s), 0.85 (3H, s).
