A general method of ene-lactam preparation is described. Ene-lactams can be prepared efficiently from keto-containing N-2,4-dimethoxylbenzylamides in good to excellent yields. This method is applicable for the preparation of substituted delta-, gamma-. and epsilon-ene-lactams and bicyclic ene-lactams.

Asymmetric and Site-Selective [3 + 2]-Annulations for the Synthesis of High-Value Bicyclic Lactams
Asymmetric and site-selective formal [3 + 2]-annulations of γ-alkyl-β,γ-unsaturated γ-lactams with α,β-unsaturated aldehydes have been developed. These organocatalysed transformations yield high value enantioenriched bicyclic γ-lactams with up to four new stereocenters (sometimes including a quarternary carbon). The overall transformation starts from simple and readily accessible furans and oversees
