By cyclocondensation of 3‐(1H‐[1,2,4]triazol‐3‐ylsulfanyl)‐pentane‐2,4‐dion with hydroxylamine, hydrazine, methylhidrazine, and arylsulfonyl‐hydrazides, the 3‐(3,5‐dimethyl‐isoxazol‐4‐ylsulfanyl)‐1H‐[1,2,4]triazole (2) and 3‐(3,5‐dimethyl‐1‐R‐pyrazol‐4‐ylsulfanyl)‐1H‐[1,2,4]triazoles (3a, 3b, 3c, 3d) are synthesized. Under the action of quaternary ammonium salts of azines with limited heating in acetone
通过将3-(1 H- [1,2,4]三唑-3-基硫烷基)戊烷-2,4-二元与羟胺,肼,甲基哒嗪和芳基磺酰肼进行环缩合,使3-(3,5-二甲基-异恶唑-4-基硫烷基)-1 H- [1,2,4]三唑(2)和3-(3,5-二甲基-1-R-吡唑-4-基硫烷基)-1 H- [1,合成2,4]三唑(3a,3b,3c,3d)。在丙酮中加热受限的情况下,在嗪的季铵盐的作用下,它们形成一系列化合物(4a,4b,4c,4d,4e,4f,4g。,4h),该分子同时包含三个不同的杂环。化合物的结构通过1 H和13 C NMR,MS和元素分析确认。研究了化合物4a,4b,4c,4d,4e,4f,4g,4h的植物生长调节活性。生物学测试的数据证明,这些化合物可能是寻找新的生长刺激剂所感兴趣的。J.杂环化学。(2010)。
