An N-heterocyclic carbene (NHC)-catalyzed highlydiastereo- and enantioselective formal [3+2] reaction of o-hydroxy aromatic aldimines and cinnamaldehydes leading to enantioenriched trans-γ-lactams was developed. Subsequent transformations allowed modifying the heterocyclic core of the products. An organocatalytic kinetic resolution of chiral lactams was demonstrated in a first proof-of-principle study
