  Enantioselective biotransformation of α,α-disubstituted dinitriles to the corresponding 2-cyanoacetamides using Rhodococcus sp. CGMCC 0497

  摘要：

  A new application of nitrile-converting enzymes in the synthesis of optically active alpha,alpha-disubstituted-alpha-cyanoacetamides from alpha,alpha-disubstituted-malononitriles with whole cells of Rhodococcus sp. CGMCC 0497 is described. The products were obtained with enantiomeric excesses of up to >99%, and yields of up to 53%. They are very useful chiral intermediates especially for the synthesis of chiral alpha,alpha-disubstituted amino acids but have never been synthesized directly by chemical or enzymatic methods.

  在二芳基膦氧化物存在下通过α-取代的丙二腈的好氧氧化制备O-保护的氰醇

  摘要：

  使用二芳基膦氧化物在O 2的存在下，实现了轻度，无氰化物的反应，并由易于获得的α-取代的丙二酸高效合成了O-膦酰基保护的氰醇。机理研究表明，除了丙二腈衍生物的初始有氧氧化外，该过程的显着特征还包括四面体中间体的形成和随后的分子内重排。可以通过醇解或通过用DIBAL-H还原来除去膦酰基保护基。

  been developed for the reductive alkylation of malononitrile with aromatic aldehydes. This new procedure has vastly improved the yield and efficiency of the process, and increased the scope of the aromatic aldehydes. Incorporating water as the catalyst in ethanol for the condensation step allows stoichiometric amounts of malononitrile and aldehyde to be employed. The reduction step takes place quickly

  已经开发了一种强大的新一锅法，用于丙二腈与芳香醛的还原烷基化。这种新工艺极大地提高了工艺的产率和效率，并扩大了芳香醛的范围。在缩合步骤的乙醇中加入水作为催化剂允许使用化学计量的丙二腈和醛。还原步骤用硼氢化钠快速有效地进行，通过过滤或萃取得到单取代的丙二腈。2-喹啉甲醛的产物迅速重排为新的中氮茚，而单取代衍生物的烷基化提供了不重排的不对称二取代丙二腈。
