Treatment of 6-anilinouracils with diethyl azodiformate led the corresponding alloxazines (benzo[g]pteridine-2,4-diones). This synthesis involves initial formation of Michael-type adducts [6-anilino-5-(1,2-bisethoxy-carbonylhydrazino)uracils] followed by dehydrogenative cyclization with further diethyl azodiformate.
