clean, mild and sustainable method for the functionalization of pyridines and their analogues is reported. A zinc‐based Lewis acid is used to activate pyridine and its analogues towards nucleophilic aromatic substitution, conjugate addition, and cyclization reactions by binding to the nitrogen on the pyridine ring and activating the pyridine ring core towards further functionalization.
据报道,有一种清洁,温和且可持续的方法使吡啶及其类似物官能化。锌基路易斯酸通过与吡啶环上的氮结合并激活吡啶环核以进一步官能化,用于活化吡啶及其类似物,以实现亲核芳香族取代,共轭加成和环化反应。
