Under ultrasound irradiation, the cyclocondensationof ethyl α-cyanocinnamates with thiourea activated by potassium carbonateat room temperature in ethanol resulted in 4-oxo-2-thioxohexahydropyrimidinesin good yields. The advantages of the procedure are short reaction period, highyield and simple work-up.

Key words: 4-oxo-2-thioxohexahydropyrimidine, synthesis, ultrasound irradiation
