Enantiomericallyenriched tosyl-protected diarylmethylamines were rapidly prepared by the asymmetricaddition of arylboronic acids to N-tosylaldimines under mild conditions in the presence of a catalyst prepared in situ from Rh(I) and a chiral diene ligand. This methodology offers access to diarylmethylamines in good yields with excellent chiral purity at room temperature using MeOH as a solvent and
