Enantio‐enriched maleimides and succinimides that can be used to prepare aza‐heterocycles with multiple chiral centers are obtained from the bicyclicguanidine‐catalyzeddirectasymmetricallylicaddition of N‐arylalkylidene‐succinimides to imines. NMR studies and deuterium‐exchange experiments were used to study the intermediates in the reaction.
