The nitroaldol reaction of (1R)-8-phenylmenthyl glyoxylate 6 with 1-nitro-2-phenylethane or with phenylnitromethane led stereoselectively to adducts 4 and 12, which where then transformed into (−)-bestatin hydrochloride and the Taxotere® side-chain in overall yields of 31 and 52%.
(1 R)-8-苯基薄荷基乙醛酸酯6与1-硝基-2-苯基乙烷或苯基硝基甲烷的硝基醛反应立体选择性地导致加合物4和12,然后将其转化为(-)-贝他汀盐酸盐和Taxotere®侧-链的总收益率分别为31%和52%。
