Abstract
The palladium-catalyzed asymmetric sulfonylation of allylic substrates rac-7a,b and rac-8a,b in the presence of the chiral phosphino-oxazoli ne ligand 3a gave the allylic sulfones 9a and 9b with ee-values of 59% and 88%, respectively, in high yield. In the presence of ligand ent-3 b the enantiomeric allylic sulfones ent-9a and ent-9b were obtained wi th ee-values of 57% and 93% in high yield.
