A new method for the preparation of 2,2-disubstituted indolinesfrom 2-phenylethylamines was developed under Pd catalysis and PhI(OAc)2 as oxidant. Imines derived from 2-pyridinecarboxaldehyde were formed in situ to direct a C–H activation process. The resulting imines were also oxidized to the corresponding amides in the same Pd-catalyzed process to obtain the final indoline as a picolinamide.
