A Pd-catalyzed ring-opening of beta-lactones with various types of amines (primary, secondary, and aryl) to provide beta-hydroxy amides with excellent selectivity toward acyl C-O bond cleavage is reported. The utility of this protocol is demonstrated in an asymmetric kinetic resolution providing enantioenriched a-methylene-beta-lactones.
