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
发现乙烯基三氟硼酸钾是用于 Rh(III) 催化环化的苯甲酰胺衍生物的有效搭档。4-三氟硼酸四氢异喹诺酮是在温和条件下生成的,在相关反应中为其他烯烃提供了区域异构互补的取代模式。这些新的含硼结构单元通过 N-芳基化衍生化,保留了硼取代基以供进一步研究。
