合成路线1
该中间体在本合成路线中的序号：(XV)Bisnaphthol (XI) was chromatographically separated into atropisomers (XII) and (XIII). The required isomer (XII) was benzylated with NaH and benzyl bromide, and the methoxymethyl group was removed by treatment with HCl, generated from acetyl chloride in MeOH, to furnish diol (XIV). Reduction of one hydroxyl group of (XIV) was then effected by the sequence of conversion to the S-methyl dithiocarbonate (XV), followed by radical deoxygenation with n-Bu3SnH and AIBN to yield (XVI). The O-benzyl groups of (XVI) were finally removed by hydrogenation over Pd/C.
