The Rh-catalyzed C–H alkylation of benzylamines with alkenes using a picolinamide derivative as a directing group is reported. Both Rh(I) and Rh(II) complexes can be used as active catalysts for this transformation. In addition, a flow set up was designed to successfully mimic this process under flow conditions. Several examples are presented under flow conditions and it was confirmed that a flow process

The first example of cobalt‐catalyzed C(sp2)−H carbonylation of benzylamines using a traceless directing group is reported, which was successfully applied to the synthesis of N−unprotected iso‐indolinones through direct C−H/N−H bonds activation. This protocol tolerates a variety of functional groups and provides a facile and efficient method for the formal synthesis of (+)‐garenoxacin.
报道了使用无痕导向基团的钴催化苄胺的C(sp 2)-H羰基羰基化的第一个实例,该实例已成功地用于通过直接CH / H / NH键活化而合成N-未保护的异吲哚啉酮。该方案可耐受多种官能团,并为(+)-加仑沙星的正式合成提供了一种简便而有效的方法。
