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.

A general and efficient method for the intermolecular direct C-7-selective C–H alkenylation of indolines using palladium(II) as the catalyst and molecularoxygen as the soleoxidant has been developed. The reaction showed complete regio- and stereoselectivity. All products were E-isomers at the C-7 position, and no Z-isomers or other position substituted products could be detected. The approach also
