Synthesis of Indolines via Pd(II)-Catalyzed Amination of C–H Bonds Using PhI(OAc)2 as the Bystanding Oxidant
摘要:
The Pd(II)-catalyzed intramolecular C-H amination of 2-pyridinesulfonyl-protected phenethylamine derivatives has been achieved using Phl(OAc)(2) as a bystanding oxidant, providing access to a variety of substituted indoline derivatives in good yields. The use of the 2-pyridlnesulfonyl protecting group allows for facile deprotection following C-H functionalization.
