The first enantioselective total synthesis of (+)-rutamarin (1) is described. The synthetic route features the highly enantioselective construction of the stereogenic center via the Sharpless asymmetric dihydroxylation (99% ee), the facile assembly of quaternary carbon-centered 3-substituted side chain and high synthetic efficiency from readily available starting materials. Furthermore, the synthetic
描述了(+)-芸香豆素(1)的第一对映选择性全合成。合成路线的特点是通过Sharpless不对称二羟基化反应(99%ee)对立体异构中心进行高度对映选择性构建,季碳中心3取代的侧链容易组装,并且易于获得的起始原料具有很高的合成效率。此外,合成策略可以容易地用于合成(+)-芸香豆素类似物。
