3-(3-吡啶基)-4-氨基-5-巯基-1,2,4-均三唑(1)与羧酸在相转移催化剂四丁基碘化铵和三氯氧磷催化作用下,高收率制得3-(3-吡啶基)-6-取代-s-1,2,4-三唑并[3,4-b]噻二唑(2a～2s).体外舒血管活性试验表明,大部分化合物具有较好的舒张生理活性.

A series of 3-(3-pyridyl)-6-substituted-s-1,2,4-triazolo[3,4-b]thiadiazoles was synthesized in good yields via condensation of 3-(3-pyridyl)-4-amino-5-thio-1,2,4-thiazoles with carboxylic acids in the presence of POCl3 and phase transfer catalyst tetrabutylammonium iodide (TBAI). The structures of the target compounds were confirmed by IR, 1H NMR, MS and elemental analyses, and the in vitro activity was also evaluated.

Key words: phase transfer catalysis, pyridyl triazolothiadiazole, synthesis, bioactivity
