  HDDA 衍生的苯与硫化物的反应：机理、模式和三组分反应

  摘要：

  我们在这里报告了烷基硫化物与通过六氢-狄尔斯-阿尔德 (HDDA) 环异构化热产生的苄的反应。最初产生的 1,3-甜菜碱（o-锍/芳基碳负离子）经历分子内质子转移以产生更稳定的 S-芳基硫叶立德。这可以以各种方式反应，包括在反应介质中加入弱酸 (HA)。这会产生瞬态离子对 ArSR2(+)A(-)，然后再生成 ArSR + RA。当使用环状硫化物时，A(-) 开环并结合到产品中，这一结果构成了多功能的三组分偶联过程。

  A unified catalytic asymmetric (N+1) (N=4, 5) annulation reaction of oxindoles with bifunctional peroxides has been achieved in the presence of a chiral phase-transfer catalyst (PTC). This general strategy utilizes peroxides as unique bielectrophilic four- or five-atom synthons to participate in the C−C and the subsequent umpolung C−O bond-forming reactions with one-carbon unit nucleophiles, thus providing
