Several novel highly symmetric carbohydrates bearing a diacylhydrazine framework have been synthesized via a five-step procedure by utilizing D-glucose, D-galactose and D-xylose as the starting materials, respectively. The target compounds have been characterized with IR, 1H NMR and elemental analysis.
