Mizoroki–Heck reaction of unstrained aryl ketone with acrylate/styrene is accomplished via palladium-catalyzed ligand-promoted C–C bond cleavage. Various (hetero)aryl ketones are compatible in the reaction, affording the alkene product in good to excellent yields. Further applications in the late-stage olefination of some drugs, natural products, and fragrance-derived aryl ketones demonstrate the synthetic utility
未应变的芳基酮与丙烯酸酯/苯乙烯的Mizoroki-Heck反应是通过钯催化的配体促进的C-C键裂解实现的。各种(杂)芳基酮在反应中是相容的,从而以良好至优异的产率提供了烯烃产物。在某些药物,天然产物和香料衍生的芳基酮的后期烯烃聚合中的进一步应用证明了该方案的合成效用。通过采用酮作为导向基团和离去基团二者,1,2- bifunctionalization经由顺序实现邻-C-H的烷基化/本位-Heck烯。
