This note describes the construction of tetrasubstituted carbon stereocenters via palladium-catalyzed allylation of sp(3) C-H bonds of 2,2,2-trifluoroethylamine derivatives. The presence of 2-pyridyl group of the imines derived from 1-substituted-2,2,2-trifluoroethylamine was key to promoting the reaction efficiently, allowing an access to a variety of 1-allylated 2,2,2-trifluoroethylamine derivatives with tetrasubstituted carbon stereocenters.
