杀虫剂Oxazosulfyl合成方法综述

A Review of the Synthesis of Oxazosulfyl

综述了新型杀虫剂Oxazosulfyl的合成工艺路线,其中路线1以3-乙硫基吡啶-2-甲酸为原料,经缩合、环合和氧化反应得到目标产物;路线2以3-乙磺酰基吡啶-2-甲酸为原料,经氯化、酰化和环合反应得到Oxazosulfyl原药。

The synthesis routes of Oxazosulfyl were summarized.The route one was prepared from 3-ethylsulfanylpicolinic acid as raw material via reactions of condensation,cyclization and oxidation.The route two was synthesized by using 3-ethylsulfonylpicolinic acid as primal raw material via chlorination,acylation and cyclization.
