一些炔菊酯类化合物的合成及其生物活性

The Synthesis and Bioactivity of Some Novel Pyrethroids

拟除虫菊酯是一类高效低毒低残留的杀虫剂，１－芳氧基－４－氯－２－丁炔类化合物具有良好的生物活性［１，２］．为了寻找结构简单、新颖、高效、低毒、低残留的拟除虫菊酯类化合物，我们用此炔类化合物与拟除虫菊酯的菊酸部分相结合，合成了１６个未见报道的化合物，并...

In order to search for the highly efficient and low toxic pyrethroids, sixteen novel compounds were synthesized by reaction of 1 aryloxy 4 chloro 2 butyne with pyrethroid acid. Their structures were confirmed by 1H NMR, IR, elementary analysis or MS. The preliminary bioassays of all compounds indicated that four of them, B 1, B 2, B 4 and B 6, showed high insecticidal activity to mosquito larva.
