The N-tosylcarboxamide group offers the possibility of directing the Pd-catalyzed C–H arylation of arenes providing a new entry to biarylcarboxamides. Moreover, its ability to react according to different reaction conditions including intramolecular reactions makes it a pivotal directing group for a divergent synthesis of biaryl-based compounds.
该Ñ -tosylcarboxamide集团提供引导芳烃提供一个新的项,以biarylcarboxamides的Pd催化的C-H芳基化的可能性。而且,其根据包括分子内反应在内的不同反应条件进行反应的能力使其成为不同的联芳基化合物合成的关键指导基团。
