Procedure

Prepared in 75% yield from 3,3:17,17-bis(ethylendioxy)androstane-6α-yl nitrate following the procedure described above for the preparation of 3,17-dioxoandrostane-6α-yl nitrate (II-aa, Prepn 1). The crude product was purified by flash chromatography (SiO2, cyclo-hexane/acetone/CH2Cl2 70/15/15) to give II-ab. 1H-NMR (300 MHz, acetone-d6, ppm from TMS): δ 5.24 (ddd, 1H), 2.72 (dd, 1H), 2.57-0.96 (m, 19H), 1.25 (s, 3H), 0.90 (s, 3H).
