  Organocatalytic Stereoselective Epoxidation of Trisubstituted Acrylonitriles

  摘要：

  The first diastereospecific and enantioselective epoxidation of trans-2-aroyl-3-arylacrylonitriles by means of the commercially available diaryl L-prolinol/tert-butyl hydroperoxide system has been developed. These diversely functionalized epoxides were obtained in excellent yield (up to 99%), complete diastereoselectivity for the transisomer, and good enantioselectivity (up to 84% ee). Highly enantioenriched epoxides can be easily obtained after a single crystallization (ee > 90%).

  An organocatalytic asymmetric cascade reaction has been developed for the synthesis of highly substituted pyrrolidines having a stereogenic quaternary centre at the 3-position. N-Tosyl aminomethyl enone and trans-α-cyano-α,β-unsaturated ketone were utilized as the reaction partners in this method. Cinchonidine derived bifunctional amino-squaramide catalysts were the best to obtain the products in high

  The stereoselective synthesis of highly functionalized tetrahydrothiophenes bearing three contiguous stereocenters, one of them quaternary, can be achieved by reacting trans-α-cyano-α,β-unsaturated ketones and trans-tert-butyl 4-mercapto-2-butenoate in the presence of a readily available amine thiourea.

  To synthesize highly substituted pyrrolidines, we developed a phosphine-catalyzed [3 + 2] annulation of β-sulfonamido-substituted enones with trans-α-cyano-α,β-unsaturated ketones. We prepared a series of pyrrolidines under mild conditions with high yields and moderate-to-good diastereoselectivities. A catalytic mechanism for this reaction is suggested.

  While phosphine-mediated reactions have been extensively explored over the past few decades, the catalytic cyclopropanation reaction via a phosphonium ylide pathway has been significantly underdeveloped, and an intermolecular version still remains to be disclosed. Presented herein is a catalytic cyclopropanation reaction between readily available benzyl bromides and activated alkenes, such as α-cyano

  尽管在过去的几十年中，膦介导的反应得到了广泛的探索，但通过鏻叶立德途径的催化环丙烷化反应还没有得到充分的开发，分子间的反应仍有待公开。本文介绍的是容易获得的苄基溴和活化烯烃（例如 α-氰基查耳酮）之间的催化环丙烷化反应，通过原位形成鏻叶立德中间体。高效地构建了一系列密集官能化的环丙烷衍生物，具有优异的非对映选择性，经过简单的转化，可以进一步转化为五元杂环化合物。此外，通过使用市售的 DuPhos 催化剂可以获得中等的对映选择性。
