A new type of cascade metallo‐ene cyclization/metallo‐carbene coupling of allenamides catalyzed by palladium is described. Allenamide substrates went through two π‐allyl palladium complex processes and migratory insertion of palladium carbene, and finally generates 2,3‐dihydropyrrole derivatives with a 1,3,8‐triene scaffold. Two new Csp3−Csp2 and Csp2−Csp2 bonds were constructed in one pot.

钯催化的烯丙酰胺的级联金属烯环化/金属碳烯偶联
描述了一种新型的钯催化的烯丙酰胺的级联金属环化/金属碳烯偶联。Allenamide底物经历了两个π-烯丙基钯络合物过程和钯卡宾的迁移插入，最终生成带有1,3,8-三烯骨架的2,3-二氢吡咯衍生物。在一个罐中构建了两个新的C sp 3 -C sp 2和C sp 2 -C sp 2键。
