2,5-二吡唑基-1,3,4-噁二唑的一锅煮法合成及生物活性

One Pot Synthesis and Biological Activity of 2,5 Dipyrazolyl 1,3,4 oxadiazoles

１，３，４－二唑类化合物具有广泛的生物生理活性，如杀菌［１］、除草［２］、杀虫［３］和消炎［４］等，而２，５－二芳基－１，３，４－二唑类化合物一般具有昆虫生长调节活性，１９８０年美国Ｄｏｗ公司报道了２，５－双（２，４－二氯苯基）－１，３，４－二...

Dipyrazolyl 1,3,4 oxadiazoles were synthesized from 5 pyrazole formic acid and its hydrazide by one pot synthetic method in the presence of phosphorus oxychloride. The method shortened synthetic route and simplified experimental operation. The preliminary biological activity tests showed that compound 3b has fungicidal and herbicidal activity.
