One‐Pot Synthesis of Ene‐Lactams viaN‐Debenzylation of Keto‐ContainingN‐2,4‐Dimethoxylbenzylamides
摘要:
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.
