Pd(II)-catalyzed aerobic oxidative intramolecular hydroamination and C–H functionalization of N-alkynyl anilines for the synthesis of indole derivatives

Add time:08/03/2019    Source:sciencedirect.com

A Pd(II)-catalyzed aerobic oxidative approach to 2,3-dihydro-1H-pyrrolo[1,2-a]indoles from simple N-alkynyl anilines through tandem intramolecular hydroamination and aryl C–H activation process has been developed. Molecular oxygen was used as the sole oxidant to recycle the Pd-catalysis. This protocol is attractive due to the available starting materials and the valuable products.
