Abstract

The palladium catalyzed asymmetric allylic sulfonylation reaction has been investigated employing β-hydroxy-and β-(o-diphenylphosphino) benzoyloxy (o-diphenyl phosphino) benzamides as chiral, non-racemic ligands. The bisphosphine β-benzoyloxybenzamide ligands proved to be the best ligands for this process. Competitive transition states for the (1S, 2R)-norephedrine derived ligand 14 are compared and a rationale is provided for the ...
