Abstract

The reaction of 1,2-diamino-4,5-diphenylimidazole with 3-aroyl-2-propanonoic acid yields 2-aroylmethyl-6,7-diphenylimidazo[1,2-b]-1,2-4-triazin-4H-3-one. The cyclization pathways of these imidazoriazines leading to condensed furo[2,3-e]-, thieno[2,3-e]-, pyrrolo[2,3-e]-, and furo[3,2-e]limidazo[1,2-b]-1,2,4-triazines were studied. A mass spectrometric study was carried out on the decomposition of these products upon electron impact.
