the gold-catalyzed reaction of vinyldiazo compounds and alkenylsilanes to produce skipped dienes, which are common structural motifs in an array of bioactive compounds. This carbon–carbon bond-forming transformation proceeds with complete regio- and stereoselectivity with the silyl group serving as a regio- and stereocontrolling element. Likewise, the use of alkynylsilanes as reaction partners yielded
我们报告了乙烯基重氮化合物和烯基硅烷的金催化反应生成跳过的二烯,这是一系列生物活性化合物中常见的结构基序。这种碳-碳键形成转化以完全的区域和立体选择性进行,甲硅烷基作为区域和立体控制元素。同样,使用炔基硅烷作为反应伙伴会产生由 C(sp)-C(sp 3 ) 偶联产生的跳过的烯炔。机械实验和 DFT 研究为逐步机制提供了支持。
