  An efficient metal-free synthesis of organic disulfides from thiocyanates using poly-ionic resin hydroxide in aqueous medium

  摘要：

  An efficient and metal-free method is described for the preparation of organic disulfides from alkyl and acyl methyl thiocyanates in the presence of poly-ionic resin hydroxide in aqueous medium. Further extension of this protocol has been tested using two different organyl thiocyanates to prepare unsymmetrical disulfides. (C) 2013 Elsevier Ltd. All rights reserved.

  reaction with thioglycolic acid gave 1,4-oxathiolan-2-one 7. While thiyl radicals easily formed by manganese(III) oxidation with ethanethiol or benzenethiol reacted with alkynes to give preferentially (E)-vinyl sulfides 10 in quantitative yields.

  考察了在1,1-二芳烃与α-巯基酮反应中使用乙酸锰（III）的第一个实例。用乙酸锰（III）在乙酸中处理乙烯和α-巯基酮的混合物，得到中等收率的环加成产物以及取代的产物。该反应可能涉及碳正离子的形成和随后的环化，以得到取代的2,3-二氢-1,4-氧杂环丁烷3。与巯基乙酸的类似反应得到1，4-氧杂硫杂环戊烷-2-酮7。尽管通过锰（III）与乙硫醇或苯硫醇的氧化而容易形成的噻吩基与炔烃反应，以定量收率优先得到（E）-乙烯基硫化物10。

  Here, we report the organocatalytic enantioselective synthesis of dihydrothiopyran derivatives from trans racemic donor-acceptor cyclopropane carbaldehydes (DACCs) and 2-mercapto-1-arylethanone via formal thio (4+2) cycloaddition involving thia-Michael aldol condensation and annulation. Mechanistic studies indicate a typical kinetic resolution (KR) is involved in this transformation, which results

  在这里，我们报道了从反式外消旋供体-受体环丙烷甲醛（DACC）和2-巯基-1-芳基乙酮，通过涉及硫杂-迈克尔羟醛缩合和环化的正式硫代（4+2）环加成，有机催化对映选择性合成二氢噻喃衍生物。机理研究表明，这种转化涉及典型的动力学拆分 (KR)，从而产生中等的产率和对映体比率。值得注意的是，该方法的特点是一锅法简单、反应条件温和、对空气和水分干扰的抵抗力强。
