  Facile synthesis of chiral 1,2-chlorohydrins via the ring-opening of meso-epoxides catalyzed by chiral phosphine oxides

  摘要：

  The facile synthesis of chiral 1,2-chlorohydrins via the enantioselective ring-opening of meso-epoxides with silicon tetrachloride in the presence of a chiral phosphine oxide was accomplished. The chiral 1,2-chlorohydrins were also obtained from the corresponding cis-alkenes in one-pot without significant loss in the selectivity, thereby permitting easy access to the 1,2-chlorohydrins from cis-alkenes with good yields and enantioselectivities.

  Four bis(tetrahydroisoquinoline) N,N′-dioxides were used as catalysts for the epoxide ring opening with tetrachlorosilane under various conditions. A strong solvent effect on asymmetric induction was observed for each of the used catalysts. The highest achieved asymmetric induction for the opening of meso-stilbene oxide was 69% ee. Regarding the cycloalkene oxides, 56% ee was obtained in the reaction with cyclooctene oxide.

  N′‐dioxide (−)‐9 has been designed, synthesized and examined as an organocatalyst in the enantioselective ring opening of meso‐epoxides using tetrachlorosilane (SiCl4). The catalyst (−)‐9 is found to exhibit good enantioselectivity for substituted cis‐stilbene epoxides; whereas, the saturated cyclic meso‐epoxides display a moderate enantioselectivity. At −30 °C in chloroform, the catalyst (−)‐9 with 0

  使用四氯硅烷（SiCl 4）设计，合成和检查了构象刚性的手性双环骨架束缚联吡啶N，N'-二氧化氮（-）- 9作为有机催化剂。发现催化剂（-）- 9对取代的顺式-二苯乙烯环氧化物具有良好的对映选择性；而，饱和环状内消旋环氧化物显示适度的对映选择性。在−30°C的氯仿中，负载量为0.5 mol％的催化剂（−）‐ 9生成氯醇，产率高达97％，ee高达93％。由于构象刚性的手性双环骨架束缚的联吡啶N，N'-二氧化物的存在，可能在高价硅物种周围产生短暂的轴向手性环境，这可能是介观中环氧化物去对称化中这种对映选择性的原因。

• Bifunctional Asymmetric Catalysis with Hydrogen Chloride: Enantioselective Ring Opening of Aziridines Catalyzed by a Phosphinothiourea
  作者：Eric Jacobsen、Tsuyoshi Mita

  DOI：10.1055/s-0029-1217344

  日期：——

  Ring-opening of aziridines with hydrogen chloride to form β-chloroamine derivatives is catalyzed by a chiral phosphinothiourea derivative in high yields and with high enantioselectivities. On the basis of (31)P NMR studies, activation of HCl appears to proceed via quantitative protonation of the catalyst to afford a phosphonium chloride complex.
