摘要: 以天然产物α-蒎烯为原料,经多步反应,合成得到9个新型α-蒎烯基苯基噻二唑类化合物7a~7i。初步探索了合成条件,并利用FT-IR、1H-NMR、13C-NMR和ESI-MS等多种手段对目标产物作了分析和表征。初步的生物活性测试表明,在50 μg/mL浓度下,目标化合物具有一定的杀菌活性,其中化合物7d对苹果轮纹病菌的抑制率达92.6%(A级活性水平),化合物7a对花生褐斑菌的抑制率达91.8%(A级活性水平)。

Abstract: Nine novel α-pinene based phenyl thiadiazole compounds 7a-7i were synthesized via a multiple step process using α-pinene as starting material.The synthetic conditions were investigated preliminarily.The targeted compounds were analyzed and characterized by FT-IR, 1H-NMR, 13C-NMR and ESI-MS.The preliminary bioassay showed that the targeted compounds exhibited a certain fungicidal activity,in which compound 7d had inhibition rate of 92.6% (A-class activity level) against Physalospora piricola, and compound 7a had inhibition rate of 91.8% (A-class activity level) against Cercopora rachidicola at the concentration of 50 μg/mL.

Key words: &alpha, -pinene, thiadiazole, synthesis, fungicidal activity
