A robust Pd(0)-catalyzed decarboxylation of allylic alkylation has been developed to construct quaternary stereocenters through the use of chiral tert-butanesulfinamide as the directing group. This strategy provides a simple and efficient route to the construction of quaternary chiral centers at the α-position of chiral sulfinamides, with high diastereoselectivities and high yields.
