该中间体在本合成路线中的序号：(XLVII)Alternatively, pyridine ester (XLI) was condensed with the organolithium reagent derived from the silyl-protected intermediate (XXI) to give the corresponding ketone (XLVI). Subsequent desilylation of (XLVI) with HF to (XLVII), followed by base-catalyzed aldol cyclization afforded (XLVIII). Then, the sequence of oxidation to acid (XLIX) with Jones reagent, followed by deoxygenation with SmI2 and basic hydrolysis provided the title diacid.
