The asymmetric miorobiologioal rednotion of the proohiral 13-ethyl-3-methoxy-8, 14-seco-Δ1,3,5(10)9(11)-estratetraen-14,17-dione (Ⅲ) with Saccharomuyces cerevisirae (2.346) was suoressful to afford an optical active key intermediate Ⅳ in an excellent yield.The D-norgestrel (Ⅰ) and D-13-ethyl norgestrienone (Ⅱ) were synthesized from this optically active intermediate (Ⅳ) via 8-step and 11-step routes, the total yields amounted to 36.6 and 10%,respectively.
