  摘要：

  The enzymatic desymmetrization/resolution of epoxydiols generated from the basic epoxidation and reduction of 1,4-naphthoquoinone, 5-hydroxy-1,4-naphthoquinone and 5,8-dihydroxy-1,4-naphthoquinone is described. 2,3-Epoxy-1(alpha),2(alpha),3(alpha),4(alpha)-tetrahydronaphthalene-1,4-diol and 5,8-diallyloxy-2,3-epoxy-1(alpha),2(alpha),3(alpha),4(alpha)-tetrahydronaphthalene-1,4-diol were desymmetrized in the presence of isopropenyl acetate using Burholderia cepacia lipase and Candida antartica lipase B, respectively. An enzymatic resolution of 8-benzyloxy-2,3-epoxy-1(alpha),2(alpha),3(alpha),4(alpha)-tetrahydronaphthalene-1,4-diol using B. cepacia lipase in isopropenyl acetate is also described.

• Ru-Catalyzed Asymmetric Hydrogenative/Transfer Hydrogenative Desymmetrization of Meso-Epoxy Diketones

  Via a strategy of asymmetric reductive desymmetrization, chiral cis-epoxy naphthoquinols with multiple contiguous stereocenters and functional groups were synthesized with excellent enantioselectivities (96–99% ee) and diastereoselectivities (8/1–15/1). A combined asymmetric hydrogenation/transfer hydrogenation mechanism was proposed based on experimental results.

  通过不对称还原去对称化的策略，合成了具有多个连续立体中心和官能团的手性顺式-环氧萘醌，具有优异的对映选择性（96-99％ee）和非对映选择性（8 / 1-15 / 1）。根据实验结果，提出了一种不对称加氢/转移加氢的联合机理。
