中文摘要：

以酰氯，2-硝基亚胺咪唑烷和2-氰基亚胺1，3-噻唑烷为主要原料，设计并合成了5个新型的2-硝基亚氨基咪唑烷（1a-1e）和10个新型的2-氰基亚氨基．1，3-噻唑烷衍生物（2a-2g，3a-3c），其结构经。HNMR和^13CNMR表征。初步生物活性测试结果表明，在浓度为20mg·L^-1时，1e和2e对苹果腐烂病菌的抑制率分别为70．69％，80．63％，对葡萄黑豆病菌的抑制率分别为58．87％，62．02％；对苹果腐烂病菌的EC∞分别为4．5mg·L^-1，8．6mg·L^-1，对葡萄黑豆病菌的EC50分别11．7mg·L^-1，14．3mg·L^-1，优于阳性对照药多菌灵。

英文摘要：

Five novel 2-nitroiminoimidazolidine （ 1a - 1e） and ten novel 2-cyaniminothiazolidine de- rivatives（2a-2g, 3a-3e） were designed and synthesized from acyl chloride, 2-nitroiminoimidazolidine and 2-cyanimino-1,3-thiazolidine. The structures were characterized by 1 H NMR and 13C NMR. The preliminary fungicidal activities tests showed that inhibition rate of le and 2e at 20 mg ·L^-1 against Valsa mali. and Sphaceloma ampelina de Bary were 58.87% and 62.02%, 58.87% and 62.02%, respectively. The ECs0 of le and 2e at 20 mg·L^-1 against Sphaceloma ampelina de Bary were 4.5 mg ·L^-1 and 8.6 mg·L^-1. The activities of le and 2e against Sphaceloma ampelina de Bary were even better than Carbendazim.
