We presented a palladium-catalyzed dominocyclization/phosphorylation of gem-dibromoolefins, which utilize H-phosphinates and secondary phosphineoxides as the phosphine sources, respectively. A variety of phosphorylated heteroaromatics were obtained in moderate to good yields with wide functional group compatibility. This one-pot reaction enables multiple bond-forming events including C−X (X=O, N
我们提出了钯催化环化多米诺/磷酸化宝石-dibromoolefins,其利用H-次膦酸酯和仲膦氧化物的混合物作为膦源,分别。以中等至良好的产率获得了多种磷酸化杂芳烃,并具有广泛的官能团兼容性。这种一锅法反应可以使用容易获得的起始材料实现多种键形成事件,包括 C-X (X=O, N, S) 和 C-P 键。此外,该协议可以轻松应用于大规模制备和后期功能化。

A modular tandem synthesis of 2-carboxybenzofurans from 2-gem-dibromovinylphenols has been established based on a sequence of Cu-catalyzed intramolecular C–O coupling and Mo(CO)6-mediated intermolecular carbonylationreactions. This protocol allowed one-step access to a broad variety of functionalized benzofuran-2-carboxylic acids, esters, and amides in good to excellent yields under Pd- and CO gas-free
