    Project supported by the Natural Science Basic Research Plan in Shaanxi Province (No. 2014JQ2064) and the Foundation for Young Scholars of Shaanxi University of Science & Technology (No. BJ12-26).

In order to develop new potent anti-phytopathogenic fungi drugs, a series of 2-sulfanylidene-2,3-dihydroquinazo- line-4(1H)-ones were synthesized under ultrasonic irradiation. Structures of the compounds were characterized by IR, 1H NMR, 13C NMR and MS. All compounds were investigated for anti-phytopathogenic fungi activity via the method of minimum inhibitory concentrations. The majority of compounds exhibited a good inhibitory activity to Alternaria brassicae and Colletotrichum gloeosporioides. The minimum inhibitory concentrations of compounds 3a, 3b, 3g and 3h were 16 μg/mL, which showed significant inhibitory activity to Alternaria brassicae compared with that of the positive control drug ketoconazole.

Key words: ultrasonic irradiation, 2-sulfanylidene-2,3-dihydroquinazoline-4(1H)-one, anti-phytopathogenic fungi activity, minimum inhibitory concentrations
