rhodium-catalyzed, site-selective C–H alkylation and arylation of pyridones using commercially available trifluoroborate reagents. This simple and versatile transformation proceeded smoothly under relatively mild conditions with perfect site selectivity. The coupling groups in the boron reagents can be extended to primary alkyl, benzyl, and cycloalkyl. Moreover, direct C–H arylation products could also be obtained
在这项研究中,我们开发了一种使用市售三氟硼酸盐试剂进行吡啶定向,铑催化,位点选择性C–H烷基化和吡啶酮芳基化的方法。这种简单而通用的转化过程在相对温和的条件下以完美的位点选择性顺利进行。硼试剂中的偶联基团可以延伸至伯烷基,苄基和环烷基。此外,也可以在相似条件下获得直接的CH芳基化产物。
