  The synthesis of chiral β-ketosulfoxides by enantioselective oxidation and their stereocontrolled reduction to β-hydroxysulfoxides

  摘要：

  Various chiral non-racemic beta-ketosulfoxides, a class of compounds frequently used in asymmetric synthesis, were prepared in good yields by tert-butyl hydroperoxide oxidation of the corresponding sulfides in the presence of a complex between titanium and (S,S)-hydrobenzoin. The ee values of almost all of the purified products were > 98%. As ascertained by X-ray analysis and/or by NMR spectroscopy, the use of the (S,S)-form of the ligand led to aryl beta-ketosulfoxides with (R-S)-configuration and to methyl phenacyl sulfoxide with the (S-S)-configuration. Some of the aryl ketosulfoxides were subjected to reduction with DIBAL-H/ZnCl2 and the corresponding beta-sulfinylalcohols with an (R,R-S)-configuration produced. (c) 2005 Elsevier Ltd.

  A switchable and benign protocol for chemoselective synthesis of sulfoxides and α-alkoxy-β-ketothioethers has been developed. It was determined that various thiophenols and alkenes/alkynes are compatible to realize the target compounds from a medium to a high yield by regulating the reaction temperature. In particular, methanol not only served as a solvent but also participated in the reaction process

  亚砜和 α-烷氧基-β-酮硫醚的化学选择性合成的可切换和良性协议已经开发。确定了各种苯硫酚和烯烃/炔烃相容，通过调节反应温度实现目标化合物从中等收率到高收率。特别是甲醇不仅作为溶剂，而且作为氢供体参与反应过程。在这项研究中，Selectfluor 已被证明是反应系统中一种高效的多功能试剂。
