Abstract

Intramolecular reductive amination of 4-keto diesters, derived from Z-Xaa-Yaa dipeptides, and subsequent γ-lactamization is a versatile method for the preparation of 3,6-dioxoperhydropyrrolo[1,2-a]pyrazines bearing amino acid side chains at C-1, C-4 and C-7 positions, as Xaa-Yaa-Zaa (Yaa ≠ Gly) tripeptide mimetics.
