PROCEDURE

实验过程

The title compound II-bn was prepared in 80% yield from 3,3:17,17-bis(ethylendioxy)-5α-hydroxy-6-(E)-methoxyiminoandrostane 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. The residue was purified by flash chromatography (SiO2, n-hexane/acetone/CH2Cl2 60/20/20). 1H-NMR (300 MHz, DMSO-d6, ppm from TMS: δ 5.47 (s, 1H), 3.75 (s, 3H), 3.02 (dd, 1H), 2.79 (d, 1H), 2.45-1.13 (m, 17H), 0.95 (s, 3H), 0.77 (s, 3H).
