HCID 690102726alpha-Methoxymethylandrostane-3,17-dioneYield 88%

Procedure

The title compound II-ae was prepared in 88% yield from 3,3:17,17-bis(ethylendioxy)-6α-methoxymethylandrostane 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 3.25 (3H, s), 3.24 (2H, m), 2.53-0.75 (21H, m), 1.11 (3H, s), 0.87 (3H, s).
