반응 단계
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. 41) 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 (m, 8H), 2.54-1.10 (m, 20H), 1.13 (s, 3H), 0.83 (s, 3H).
