Vorschrift

7β-Hydroxymethylandrostane-3,17-dione II-aw was prepared in 85% yield from 3,3:17,17-bis(ethylendioxy)-7β-hydroxymethylandrostane 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 3.70-3.60 (2H, m), 3.54 (1H, t), 2.50-0.90 (21H, m), 1.06 (3H, s), 0.86 (3H, s).
