α－羰基－α－（1H－1，2，4－三唑－1－基）乙烯基芳基酮衍生物的合成及生物活性研究

Synthesis of α-Oxo-α-(1H-1,2,4-triazo-1-yl) Ketene N,S-Acetals and Their Biological Activities

α－（１Ｈ－１，２，４－三唑－１－基）取代苯乙酮与异硫氰酸苯酯在强碱条件下经缩合、卤化后得到含三唑的烯酮氮硫缩醛化合物１．该化合物与各种卤代物反应，形成了包括五元、六元杂环的缩合产物。部分结构具有一定的植物生长调节活性。

The reaction of α-(1H-1,2,4-Triazol-1-yl) substituted acetophenone with isothiocyanate in the presence of a base and subsequent alkylation afforded twenty-six new α-ox-oketene N,S-acetals containing 1H-1,2,4-Triazole. Their structures were confirmed by IR,￣1H NMR, elementary analysis. The preliminary biological test showed that some componds obtained have plant-regulatory activities.
