The synthesis of some (methyl)glyoxal 1,2-bis(acylhydrazones) (1, 3-6) and their cyclization into the title compounds (7-10) under acetylating conditions are described. The stereostructures of the new bi-heterocyclic diastereomers were studied by 1H- and 13C-NMR measurements as well as by X-ray analysis.
