含氟、杂环、手性是现代农药领域中新药合成的三大特征。含氟杂环化合物的种类非常多,由于受合成技术的限制,目前应用最多的是吡啶类含氟化合物。吡啶类含氟化合物具有含氟、含氮杂环两种特征,它们与一些手性中间体结合所形成的具有含氟、含氮杂环、手性等三大特征的化合物是最近几年农药领域中研究和应用非常广泛的一类化合物。卤代吡啶类化合物中除了氟化物外,一些含氯、含溴和少量含碘的化合物作为 Fluorine, heterocyclic, chirality is the three characteristics of new drug synthesis in the field of modern pesticides. Fluorinated heterocyclic compounds are many types, due to the limitations of the synthesis technology, the most widely used is pyridine fluorochemicals. Pyridine Fluorinated Compounds Containing Fluorine and Nitrogen-Containing Heterocycles Two compounds with the three major characteristics of fluorine, nitrogen-containing heterocycles and chirality formed by their combination with some chiral intermediates are pesticides in recent years In the field of research and application of a very wide range of compounds. In addition to fluoride compounds in the halopyridines, some chlorine, bromine and a small amount of iodine containing compounds as
