Malonic acid undergoes condensation readily with ureas to yield barbituric acids 2, which on bromination give 5,5-dibromobarbituric acids 3. Reaction of α-D-galactose with these 5,5-dibromo barbituric acids afforded 2,3-α-D-galactopyrano-1,4-dioxo-7,9-diaza-spiro[4,5]deca-6,8,10-triones 4. The structures of the products have been assigned on the basis of 1H NMR, 13C NMR, FAB-MS, optical activity, and elemental analysis. The title compounds are found to have antibacterial and antifungal activities.
