実験手順

The title compound II-ap was prepared in 88% yield from 3,3:17,17-bis(ethylendioxy)-6α-methoxymethylandrostane by the procedure described above for the preparation of 6α-cyanoandrostane-3,17-dione (II-ac, Prepn. 3). 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 (s, 3H), 3.24 (m, 2H), 2.53-0.75 (m, 21H), 1.11 (s, 3H), 0.87 (s, 3H).
