Palladium-Catalyzed Tandem N-Arylation/Carboamination Reactions for the Stereoselective Synthesis of <i>N</i>-Aryl-2-benzyl Pyrrolidines

Abstract

[reaction: see text] The tandem N-arylation/carboamination of gamma-amino alkenes with two different aryl bromides provides rapid entry to differentially arylated N-aryl-2-benzyl pyrrolidine derivatives in good yields with good to excellent levels of diastereoselectivity. The selective diarylation is achieved in a one-pot process by an in situ modification of the palladium catalyst via phosphine ligand exchange.
