Under selected conditions, the Zr-catalyzed reaction of EtMgCl with imines produces C,N-dimagnesiated compounds, which can be further trapped with electrophiles. The overall transformation provides a new route to bifunctional or cyclic nitrogen-containing compounds. Particularly, 1-azaspirocyclic γ-lactams, pyrrolidines and azetidines can be obtained in this way.
