A novel approach was developed for the preparation of 4,6-disubstituted-1,2-dihydro-2-oxo-3-pyridinecarboxylic ester in moderate to good yields. This route involves a reaction sequence of Michael addition, transformation to ene-lactam, and aromatization, featuring easily available material, variable substituents, and good functional compatibility.
开发了一种新方法用于制备4,6-二取代-1,2-二氢-2-氧-3-吡啶羧酸酯,产率中等到良好。该路线涉及迈克尔加成、转化为烯内酯和芳构化的反应序列,特点是使用的材料易得、取代基可变且功能兼容性良好。
