合成路线1
该中间体在本合成路线中的序号：(XVIII)Ketone (XVI) was treated with phenylselanyl chloride and LHMDS yielding the selenium derivative (XVII). Enone (XVIII) was then produced by oxidative elimination of the selenide (XVII). Reduction of the unsaturated ketone (XVIII) with NaBH4 in the presence of CeCl3 gave the 3-beta-allylic alcohol (XIX). This was acylated with myristoyl chloride (XX) to afford ester (XXI). Finally, acid deprotection of the silyl ether and the p-methoxyphenyl acetal of (XXI) furnished the title compound.
