Deskripsi
The reaction of nitrilimine 6a with ethyl pyridine-2-acetate (7) gave thecorresponding pyrrolo[1,2-a]pyridine 8, while the reaction of 6b containing an estermoiety afforded the acyclic adduct 9. The reaction of 6a with 2-aminopyrimidine (10)gave the novel unexpected pyrimido[2,1-d]1,2,3,5-tetrazine 11. Acyclic adducts 16 and17 were obtained from the reaction of 6b with 2-cyanomethylbenzimidazole (14) and 2-aminobenzimidazole (15), respectively.
