A variety of N‐(furan‐3‐ylmethylene)benzenesulfonamides were obtained by a gold(I)‐catalyzed cascade reaction from easily accessible starting materials. The reaction pathway involves a rarely observed 1,2‐alkynyl migration onto a gold carbenoid. This observation further enriches gold carbenoid chemistry with regard to group migration.
通过金(I)催化的级联反应,从容易获得的起始原料中获得了各种N-(呋喃-3-基亚甲基)苯磺酰胺。该反应途径涉及很少见的1,2-炔基迁移到金类胡萝卜素上。该观察结果进一步丰富了关于类迁移的金类化学物质。
