A Pd-catalyzed methodology for the preparation of tertiary enamides from acyclic secondary amides and bromo acrylates under mild reaction conditions has been developed using [Pd2(dba)3], XantPhos, and Ag2CO3 as a base. The reaction occurs through a stereospecific metal-mediated oxidative-insertion mechanism.
使用[Pd 2(dba)3 ],XantPhos和Ag 2 CO 3作为碱,开发了在温和的反应条件下由无环仲酰胺和溴丙烯酸酯制备叔烯酰胺的Pd催化方法。该反应通过立体定向金属介导的氧化插入机制发生。
