Novel N-benzoyl-N'-phenylthioureas containing imidazolidine-2,4-dione were prepared from substituted benzoyl chlorides via isothiocyanate formation followed by treatment with 5-(4-aminophenyl/benzyl)imidazolidine-2,4-dione. The base-catalyzed condensation of thioureas with bromoacetone was carried out in the presence of triethylamine to afford the corresponding 4-methyl-3-substituted-phenyl-2-acylimine thiazolines in moderate to good yields. The corresponding thiazolines were characterized by IR, 1H NMR, HR-ESI-MS spectroscopic data and X-ray diffraction analyses, and the mechanism of thiourea reacting with bromoacetone was re-confirmed by the X-ray structures of compounds 3g and 4g. The thiazolines were evaluated their biological activities, and some of them exhibited significant activities such as compounds 3i and 4q having 82.6% and 100% mortality against P. xylostella at the concentration of 200 mg/L, 4n having 82.6% inhibitory rate against S. scleotiorum at 50 μg/mL, and slight but not significant herbicidal activities.

Key words: hydantoin, 4-methyl-3-phenyl-2-acylimine thiazoline, antifungal activity, insecticidal activity
