Visible-light-induced β-carbonyl alkylation of pyridines was developed by employing various cyclopropanols and N-amidopyridinium salts under mild conditions. This method provides an effective tool for the synthesis of valuable β-pyridyl-functionalized carbonyl frameworks with excellent C4 selectivity and the late-stage functionalization of complex and medicinally relevant molecules.
通过在温和条件下使用各种环丙醇和N-氨基吡啶鎓盐开发了可见光诱导的吡啶 β-羰基烷基化。该方法为合成有价值的 β-吡啶基官能化羰基骨架提供了一种有效的工具,该骨架具有优异的 C4 选择性以及复杂和药用相关分子的后期官能化。
