The optically active taxol A-ring unit 3 was synthesized in 11 steps from 2-isopropyl-2-propenol. The stereogenic centers were introduced via the asymmetric glyoxylate-ene reaction and the Sharpless asymmetric epoxidation reaction.
光学活性紫杉醇A-环单元3由2-异丙基-2-丙烯醇以11个步骤合成。立体异构中心通过不对称乙醛酸-烯反应和Sharpless不对称环氧化反应引入。
