Palladium‐Catalyzed Diastereoselective α‐Allylation of Chiral Sulfinimines
The first diastereoselective allylation reaction at the α-position of ketones by using tert-butanesulfinamide as a chiral auxiliary is explored. Excellent yields and high diastereomeric ratios were achieved under palladium catalysis in the presence of a readily available achiral phosphine ligand. The chiral auxiliary was removed in quantitative yield under the optimized conditions without any racemization.
