We found that N-(tert-butyl)-N-methylanilines 1 have C(aryl)–N(amine) bond axial chirality and succeeded the optical resolution of C–N bond atropisomers of amines 1 by a chiral palladium resolving agent and/or a chiral HPLC method. Finally, we demonstrated the ability of chiral amines 1 as a ligand in palladium-catalyzed asymmetric allylic alkylation of allylic esters with malonates (up to 95% ee).
