Pd(II)-catalyzed aerobic oxidative intramolecular hydroamination and C–H functionalization of N-alkynyl anilines for the synthesis of indole derivatives
摘要:
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. (C) 2013 Elsevier Ltd.

types of hydrogen transfer processes ([1,5]-hydride shift, proton transfer, and [1,2]-hydride shift) occurred to give various 3-alkoxycarbonylindoles. Further study revealed that a [1,2]-alkyl shift instead of a [1,2]-hydride shift proceeded to afford 3-alkylindoles from the substrates with an amino group having tertiary carbons adjacent to a nitrogenatom.
