New, stable α-amido-α-aminonitrones were obtained in good yields from 3-oxobutyric acid N-pyridin-2-ylamides and nitrosobenzene. The α-amido-α-aminonitrones were then used as new, versatile building blocks to obtaining various heterocycles with both bielectrophilic and binucleophilic reagents. With diiodomethane as reagent, 1,2,5-oxadiazine derivatives were formed, whereas reactions with aromatic 1,2-, 1,3- and 1,4-diamines yielded quinoxaline, quinazoline, perimidine, and dibenzo[d,f][1,3]diazepine derivatives, respectively.
