摘要
以5-(4-羟基/氨基苄基)-2-硫代-2,4-咪唑啉二酮为原料,在三乙胺作傅酸剂的条件下与取代磺酰氯反应,得到28个新的5-(4-羟基/氨基苄基)-2-硫代-2,4-咪唑啉二酮苯磺酸酯/酰胺类化合物,它们的化学结构经1H NMR,MS和元素分析确证.初步生测结果表明:在100μg/mL浓度下,部分目标化合物均对供试植物病原菌和油菜显现出一定的抑制活性,如5-(4-氨基苄基)-2-硫代-2,4-咪唑啉二酮对碘苯磺酰胺(4d)对黄瓜灰霉病菌抑制率为80.7%,5-(4-羟基苄基)-2-硫代-2,4-咪唑啉二酮邻甲基苯磺酸酯(3n)和5-(4-氨基苄基)-2-硫代-2,4-咪唑啉二酮-2,4-二氯苯磺酰胺(4m)对油菜的生长抑制率分别为87.4%和81.5%.
Novel 5-(4-hydroxy/aminobenzyl)-thiohydantoin phenylsulfonates/phenylsulfonamides were prepared using 5-(4-hydroxy/aminobenzyl)-thiohydantoin and substituted phenylsulfonyl chlorides as raw materials. Their structures were confirmed by ^1H NMR, MS spectra and elementary analysis. The preliminary bioassay results showed that some of them have certain fungicidal and herbicidal activities. For example, 5-(4-aminobenzyl)-thiohydantoin 4-iodophenylsulfonamide (4d) had 80.7% inhibition rate against Botrytis cinerea, 5-(4-hydroxybenzyl)-thiohydantoin 2-methylphenylsulfonate (3n) and 5-(4-aminobenzyl)-thiohydantoin 2,4-dichlorophenylsulfonamide (4m) had 87.4% and 81.5% inhibition rates against Brasica campestris at the concentration of 100 μg/mL, respectively.
