Pd-catalyzed β-C-H functionalizations of carboxylic acid derivatives using an auxiliary as a directing group have been extensively explored in the past decade. In comparison to the most widely used auxiliaries in asymmetric synthesis, the simplicity

An intermolecular C(sp(3))-H amination using a Pd(0) /PAr3 catalyst was developed. The reaction begins with oxidative addition of R2 N-OBz to a Pd(0) /PAr3 catalyst and subsequent cleavage of a C(sp(3))-H bond by the generated Pd-NR2 intermediate. Th
