describes the development of Rh-catalyzed [2,3]-sigmatropic rearrangement of alkynyl carbenes with allyl sulfides. The protocol exhibits equitable functional group tolerance and allows the formation of a variety of synthetically valuable sulfide-substituted 1,5-enyne products. To the best of our knowledge, this is the first example of [2,3]-sigmatropic rearrangement of alkynyl carbenes. DFT analysis supports
本研究描述了 Rh 催化的炔基卡宾与烯丙基硫化物的 [2,3]-σ 重排反应的进展。该方案表现出公平的官能团耐受性,并允许形成各种具有合成价值的硫化物取代的 1,5-烯炔产品。据我们所知,这是炔基卡宾[2,3]-σ重排的第一个例子。DFT 分析支持铑卡宾生成、锍叶立德形成和[2,3]-σ重排途径的参与。
