Ten derivatives of octahydro-quinazoline-2, 5-dione were synthesized from aromatic aldehyde ,dimedone and urea or thiouerea using an ultrasound technique and using zirconium oxy nitrate hydrate as a new catalyst. The new compounds were proved upon elemental and spectroscopic analyses of FTIR, 1H, and 13C-NMR together with their physical properties
