The first example of cobalt-catalyzed selective bis-alkynylation of amides via double C–H bond activation with the directing assistance of a removable bidentate auxiliary is reported. The developed alkynylation strategy is simple, efficient, and tolerant of various functional groups including ether, amine, halides, and heterocyclic motifs. The reaction can be scaled up under mild conditions.
据报道,第一个例子是在可移动的双齿助剂的指导下,通过双CH键活化钴的酰胺选择性双烷基酰胺化反应。发达的炔基化策略简单,有效,并且可以耐受各种官能团,包括醚,胺,卤化物和杂环基序。该反应可以在温和的条件下扩大规模。
