合成路线1
该中间体在本合成路线中的序号：(XIII)Alkylation of the allylic alcohol (IX) with tert-butyl bromoacetate (X) under phase-transfer conditions afforded ester (XI), which was then converted into chloro derivative (XII) by treatment with a mixture of CH3CN/CCl4/pyridine and then PPh3. Acidic cleavage of the tetrahydropyranyl ether groups of (XII) led to the dihydroxy derivative (XIII), which was finally subjected to saponification with LiOH in MeOH to yield the desired product.
