该中间体在本合成路线中的序号：(CVIII)In a further synthetic procedure, ketalization of enone (CV) with ethyleneglycol afforded (CVI). After silylation of the primary alcohol group of (CVI) to (CVII), allylic oxidation by means of tert-butyl hydroperoxide and Cr(CO)6 furnished ketone (CVIII). Catalytic hydrogenation of the double bond of (CVIII) to (CIX), followed by ketone reduction with K-Selectride, gave the C-7 alcohol (CX), which was esterified with benzoyl chloride, yielding benzoate ester (CXI). Subsequent desilylation of (CXI) using tetrabutylammonium fluoride provided (CXII).
