Significance

An organocatalyzed asymmetric aza-ene-type reaction of N-benzoylimines and ene­carbamates is described. A chiral 3,3′-disubstituted phosphoric acid allows the formation of β-aminoimine derivatives, which can be transformed to 1,3-diamines in good yields and up to 98% ee (15 examples, 0.1 mol% catalyst, r.t., 5 h).
