Potassium vinyltrifluoroborate was found to be an efficient partner with benzamide derivatives for Rh(III)-catalyzed annulations. 4-Trifluoroboratotetrahydroisoquinolones were generated under mild conditions, affording a regioisomerically complementary substitution pattern to other alkenes in related reactions. These new boron-containing building blocks were derivatized by N-arylations, retaining the boron substituent for further elaboration.
发现乙烯基三氟硼酸钾与苯甲酰胺衍生物是 Rh(III)催化环化反应的有效搭档。在温和条件下生成了 4-三氟硼酸盐四氢异喹啉酮,提供了与相关反应中其他烯烃不同的区域异构体互补取代模式。这些新的含硼砌块可通过 N-芳基化进行衍生化,保留硼取代基以进行进一步的修饰。
