  Stereoselective addition reactions of chiral N-benzylidene-p-toluenesulfinamides. Asymmetric syntheses of .beta.- and .gamma.-amino acids

  摘要：

  Chiral N-benzylidene-p-toluenesulfinamides 2 were prepared by the reaction of benzonitrile with alkyllithium in ether followed by (-)-l-menthyl (S)-p-tolylsulfinate. Treatment of 2 with allylmagnesium bromide in ether at 0-degrees-C gave the adducts (R)-7 with excellent stereoselectivity. Pure chiral sulfinamides 7 were converted into chiral beta- and gamma-amino acids in four and five steps, respectively.

  transsulfinamidation of primary sulfinamides with alkyl, aryl, and heterocyclic amines for the synthesis of diverse secondary and tertiary sulfinamides has been realized. Unlike transition metal-catalyzed cross-coupling approaches restricted to non-commercially available disubstituted O-benzoyl hydroxylamines, this newly developed protocol is suitable for diverse readily available primary and secondary amines without

  已经实现了伯亚氨基酰胺与烷基，芳基和杂环胺的稀土催化的转磺酰胺化反应，用于合成各种仲和叔亚氨基酰胺。与过渡金属催化的交叉偶联方法仅限于非商业可用的二取代的O-苯甲酰基羟胺不同，该新开发的方案适用于各种易于获得的伯胺和仲胺，无需进行任何修改。Eu（OTf）3在温和的反应条件下具有优异的催化活性和选择性，从而扩展了稀土催化的适用性。
