for converting para-substituted pyridine rings into meta-dialkylamino-substituted benzene rings through sequential ring-opening and ring-closing reactions. The nitrogen atom in the pyridine rings was replaced with a methine group, and a dialkylamino substituent was introduced onto the original unsubstituted carbon atom in the pyridine rings. This process can be formally regarded as a hybrid of the skeletal
在此我们报告了一种通过顺序开环和闭环反应将对位取代的吡啶环转化为间位二烷基氨基取代的苯环的方法。吡啶环中的氮原子被次甲基取代,并且二烷基氨基取代基被引入到吡啶环中原始未取代的碳原子上。这个过程可以正式被视为吡啶环的骨架编辑和 C-H 胺化的混合体。
