Palladium-catalyzed enantioselective arylation of trichloro- or tri-/difluoroacetaldimine precursors

Chem Commun (Camb). 2024 Mar 19;60(24):3303-3306. doi: 10.1039/d4cc00022f.

Abstract

A palladium-catalyzed asymmetric α-arylation of N-carbamoyl imine precursors containing CCl3, CF3 and CF2H is presented. This protocol provides facile access to a series of chiral α-aryl trichloroethylamines bearing various functional groups, with moderate to high yields (40-82% yield) and high enantioselectivity (80-99% ee).
