合成路线1
该中间体在本合成路线中的序号:(XCVIII)Birch reduction of enone (XCVII), followed by reduction of the saturated ketone (XCVIII) with K-Selectride, provided alcohol (XCIX). Acetylation of (IC) gave the triacetate (C). Selective hydrolysis of the C-3 acetate group of (C) with NaCN in MeOH yielded alcohol (CI), which was oxidized to ketone (CII) by using the Jones reagent.
