摘　　要：以2-氨基-5-烃基-1,3,4-噻二唑和水杨醛为原料,分别用"分步法"和"一锅法"经还原中间产物Schiff碱的CN双键合成了一系列2-((1,3,4-噻二唑基)胺甲基)苯酚类新化合物,"一锅法"的产率较高,为56%～80%。产物的结构用IR、1H NMR、13C NMR和MS进行了表征。初步测试了目标化合物的杀菌活性,证明化合物对赤星病菌具有较好的抑菌活性,当浓度为25 mg/L时,化合物3i的抑制率为76%,化合物3f、3h、3k和3l的为70%。A series of 2-（1,3,4-thiadiazolylaminomethyl） phenols was synthesized by reducing the C=N double bond of the intermediate Schiff bases prepared from the reaction of 2-amino-5-alkyl （ aryl ） -1,3,4- thiadiazoles and salicylaldehyde v/a either fractional step method or one-pot process. The yields, of the products obtained from one-pot synthesis were higher and in the range of 56% - 80%. The structures of the products were characterized by means of IR, 1H NMR, 13C NMR and MS. The fungicidal activity of the title compounds was evaluated preliminarily, some of which exhibited moderate activity against Alternaria alternata. The inhibitory rate of compound 3i was 76% at the concentration of 25 mg/L, and 70% for compounds 3f, 3h, 3k and 31.
