吡嘧磺隆的合成

Synthesis of Pyrazosulfuron-ethyl

由氰乙酸乙酯出发 ,经过四步反应合成出吡嘧磺隆 ,同时介绍了各中间体的合成 .在实验过程中 ,根据核磁共振谱、红外光谱对所合成化合物的结构进行了证实 。

This paper reports the synthesis of pyrazosulfuron ethyl and its intermediates. During making experiments, the structure of compounds which have been synthesized were confirmed by 1 H NMR and IR, the content of components was mesured by GC and LC.
