실험 절차

17,17-Bis(ethylendioxy)-7-(E)-hydroxyiminoandrostane was prepared in 95% yield from 3,3:17,17-bis(ethylendioxy)androstan-7-one by the procedure described above for the preparation of 3,3:17,17-bis(ethylendioxy)-6-(E)-hydroxyiminoandrostane (Prepn. 18). The crude product was purified by flash chromatography (SiO2, CH2Cl2/MeOH 9/1). 1H-NMR (300 MHz, DMSO-d6, ppm from TMS: δ 10.17 (1H, s), 3.88-3.70 (8H, m), 2.89 (1H, m), 2.23-0.71 (19H, m), 0.90 (3H, s), 0.77 (3H, s).
