Sarcosinanhydride-monolactamacetal (7) furnishes an equilibrium concentration of the electronically activated tetrahydropyrazine 3b which yields in contrast to other pyrazine derivatives with 4-nitrophenylazide (4) the cycloaddition product 9.Catalytic cleavage of 9 leads to the triazene compound 11. - Key words: Lactam Acetals, Heterocyclic Synthesis, Cycloaddition Reactions, Triazene
