Selective Palladium(II)‐Catalyzed Carbonylation of Methylene β‐C−H Bonds in Aliphatic Amines

Abstract

Palladium(II)-catalyzed C-H carbonylation reactions of methylene C-H bonds in secondary aliphatic amines lead to the formation of trans-disubstituted β-lactams in excellent yields and selectivities. The generality of the C-H carbonylation process is aided by the action of xantphos-based ligands and is important in securing good yields for the β-lactam products.
