合成路线1
该中间体在本合成路线中的序号：(XIV)Elimination of the sulfate group of (XI) with DBU in refluxing toluene led, after acidic workup, to the formation of the allylic alcohol (XII). Oxidative cleavage of the p-methoxyphenyl acetal of (XII) with DDQ produced regioselectively the p-methoxybenzoate ester (XIII). Further treatment of (XIII) with p--anisaldehyde dimethyl acetal (VII) gave the acetal (XIV). Ester hydrolysis of (XIV), followed by oxidation of the resulting alcohol (XV) with Dess-Martin periodinane afforded ketone (XVI).
