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。
