Palladium-catalyzed diastereoselective synthesis of optically active β,β-diarylpropionic acid derivatives employing 4-(tert-butyl)oxazolidin-2-one as the chiral auxiliary under an air atmosphere in excellent yields with high diastereoselectivity is reported. The catalytic system is applied to the total synthesis of (R)-tolterodine and the enantiomer of a key intermediate for MK-8718.
