  Oxidation of Organotrifluoroborates via Oxone

  摘要：

  A method for the oxidation of organotrifluoroborates using Oxone was developed. A variety of aryl-, heteroaryl-, alkenyl-, and alkyltrifluoroborates were converted into the corresponding oxidized products in excellent yields. This method proved to be tolerant of a broad range of functional groups, and in secondary alkyl substrates it was demonstrated to be completely stereospecific.

  日期：——

  In this study, we report a highly stereoselective addition of sulfur-containing heterocyclic compounds to isatin-derived ketimines efficiently catalyzed by cinchonidine-derived bifunctional tertiary aminothiourea (1 mol%). This organocatalytic methodology furnishes a new type of optically active heterocyclic compound with two adjacent chiral quaternary carbon stereocenters in good yield (up to 98%)

  在这项研究中，我们报告了由辛可尼定衍生的双官能叔氨基硫脲（1 mol％）有效催化的高选择性立体选择性地将含硫杂环化合物添加到由isatin衍生的酮亚胺中。这种有机催化方法可提供一种新型的旋光杂环化合物，其具有两个相邻的手性季碳立体中心，收率好（高达98％），非对映选择性（高达20：1 dr）和高对映选择性（高达95％ee） 。
