実験手順

17,17-Bis(ethylendioxy)androstane-7-one was prepared in 82% yield from 3,3:17,17-bis(ethylendioxy)-5-androsten-7-one by the procedure described above for the preparation of 3β-acetoxyandrostane-7,17-dione (Prepn. 29) using EtOAc instead of EtOH. The crude product was purified by flash chromatography (SiO2, n-hexane/EtOAc 6/4). 1H-NMR (300 MHz, acetone-d6, ppm from TMS: δ 3.96-3.75 (8H, m), 2.54-1.10 (20H, m), 1.13 (3H, s), 0.83 (3H, s).
