Based on the structure of hydantocidin as a leading compound, the natural inhibitor of AdSS, its activated hydantocidin 5'-phosphate in the plant and 5-substituted 2,4-imidazo-lidinedione esters as the second leading compound, thirty eight new (thio)phosphate derivatives with hydantoin were synthesized by the reaction of (thio)phosphoryl chloride with 5-(4-hydroxyphenyl)- and 5-(4-hydroxybenzyl)-2,4-imidazolidinedione intermediates, and their structures were confirmed by IR, 1H NMR, 31P NMR spectra and elemental analysis. The preliminary bioassay showed that O-ethyl-O-phenyl-5-(4-hy- droxyphenyl)-2,4-imidazolidineone thiophosphate (B14) and O,O-diphenyl-5-(4-hydroxybenzyl)-2-thio-4-imidazolidineone thiophosphate (B25) have an inhibitory ratio 53.1% and 62.7% against Brasica campestris at the concentration of 100 μg/mL, while O,O-di(o-methoxyphenyl)-5-(4-hydroxyphenyl)-2,4-imidazolidineone thiophosphate (B7), B14 and O,O-di(p-methyl- phenyl)-5-(4-hydroxybenzyl)-2,4-imidazolidineone thiophosphate (B17) showed 52%, 51% and 69% insecticidal activities against Myzus Persicae at the concentration of 300 μg/mL.
