摘要:

以2-巯基-5, 7-二甲基-1, 2, 4-三唑并[1, 5-a]嘧啶为原料,设计合成了10种含5, 7-二甲基-1, 2, 4-三唑并[1, 5-a]嘧啶环和1, 2, 4-三唑环的双杂环硫醚化合物,结构经MS、1H NMR进行表征。初步的生物活性测试表明,在50×10-6 g/L浓度下,大部分化合物6对甜菜褐斑病菌表现出好的抑制效果, 化合物6b、6e、6f、6g、6h抑制效果达到A级(≥90%)。

Abstract:

Ten novel diheterocyclic thio-ether compounds containing 1, 2, 4-triazolo[1, 5-a] pyrimidine and 1, 2, 4-triazole moieties were designed and synthesized by using 2-mercapto-5, 7-dimethyl-[1, 2, 4]triazolo[1, 5-a]pyrimidine as starting material. All compounds obtained were comfired by MS and 1H NMR, Preliminary biological activity indicates most compounds 6 display good activity against C. beticola. Especially, 6b, 6e, 6f, 6g, 6h at the concentration of 50×10-6 g/ can reach grade A (≥90%).

Key words: triazolopyrimidine, triazolo, synthesis, biological activity
