  The highly enantioselective transformation of silylketenes into α-silylthioesters catalysed by cinchona alkaloids

  摘要：

  The reaction of silylketenes with thiophenol, mediated by cinchona alkaloid catalysts, proceeds to give alpha -silylthioester products in good chemical yield and with enantiomeric excess values in the range 79-93%. The absolute configuration of one of the thioester products was determined by X-ray diffraction. (C) 2001 Elsevier Science Ltd. All rights reserved.

  Trimethylsilylacetic acid readily forms the dianion (2) providing highly efficient routes to α-trimethylsilylcarboxylic acids, α,β-unsaturated acids, and α-trimethylsilyl-γ-butyrolactones; the latter can then be converted into α-ylidene-γ-butyrolactones, α-bromo-γ-butyrolactones and γ-butyrolactones.

  三甲基甲硅烷基酸容易形成二价阴离子（2），提供了高效的途径来合成α-三甲基甲硅烷基羧酸，α，β-不饱和酸和α-三甲基甲硅烷基-γ-丁内酯；然后可以将后者转化为α-亚烷基-γ-丁内酯，α-溴-γ-丁内酯和γ-丁内酯。

  on both reaction components. Solely [2 + 2] cycloaddition products are observed when using α,β-substituted trifluoromethylenones or α-trialkylsilyl acetic acid derivatives; both [2 + 2] and [4 + 2] cycloaddition products are observed when using β-substituted trifluoromethylenones and α-alkyl-α-trialkylsilyl acetic acids as reactants, with the [2 + 2] cycloaddition as the major reaction product. The beneficial

  已开发出异硫脲催化的 C(1)-烷基和 C(1)-未取代的烯醇铵与 β- 和 α,β-取代的三氟亚甲基酮的区域和对映选择性形式 [2 + 2] 环加成反应。在所有情况下，观察到[2 + 2]-环加成优先于替代的[4 + 2]-环加成，使β-内酯具有优异的非对映选择性和对映选择性（34个例子，高达>95:5 dr，>99： 1 呃）。该过程的区域选择性取决于两种反应组分上取代基的性质。当使用α,β-取代的三氟亚甲基酮或α-三烷基甲硅烷基乙酸衍生物时，仅观察到[2+2]环加成产物；当使用β-取代的三氟亚甲基酮和α-烷基-α-三烷基甲硅烷基乙酸作为反应物时，观察到[2+2]和[4+2]环加成产物，以[2+2]环加成作为主要反应产物。该方案中酸组分内的 α-甲硅烷基取代基的有益作用已通过对照实验得到证明。
