拟除虫菊酯是在研究天然除虫菊酯化学的基础上发展起来的一类高效、低毒、广谱杀虫剂。其中,溴氰菊酯(Deltamethrin)是活性较高,光稳定性较好的一种菊酪类杀虫剂,它是具有[1R cis.αs]构型的单一光学异构体。生产溴氰菊酯的关键中间体是(1 R-cis-)
Pyrethroids are highly effective, low-toxicity, broad-spectrum insecticides developed on the basis of the research on natural pyrethroid chemistry. Among them, deltamethrin is a kind of pyrethroid insecticide with high activity and good photostability, which is a single optical isomer with [1R cis.αs] configuration. The key intermediate for deltamethrin production is (1 R-cis-)
