Synthesis of Optically Active Atropisomeric Anilide Derivatives through Diastereoselective N-Allylation with a Chiral Pd−π-Allyl Catalyst

N-Allylation of o-tert-butyl anilides derived from o-tert-butyl aniline and (S)-lactic acid or (S)-mandelic acid proceeded with high diastereoselectivity in the presence of a (BINAP)Pd−π-allyl catalyst to give atropisomeric N-allyl o-tert-butyl anilide derivatives.
