Remote Control of Axial Chirality: Aminocatalytic Desymmetrization of N‑Arylmaleimides via Vinylogous Michael Addition

Remote control of the axial chirality of N-(2-t-butylphenyl)­succinimides was realized via the vinylogous Michael addition of 3-substituted cyclohexenones to N-(2-t-butylphenyl)­maleimides. 9-Amino­(9-deoxy)epi-quinine promoted the enantioselective desymmetrization, leading to atropisomeric succinimides with two adjacent stereocenters.
