原文开头
Long-Hai Li, Shiwei Su, Xian Zheng, Lumin Zhang* Given the prevalence of nitrogen heterocycles in pharmaceuticals, divergent skeletal editing techniques that enable rapid access to a diverse library of azacycles from a single substrate are highly desirable. Herein, we report a skeletal editing approach that converts abundant saturated primary amines into N-heterocycles, with exceptional functional-group compatibility, broad skeletal diversity, superior regioselectivity, and diastereospecificity (both >20:1). By harnessing the reactivity of hypervalent iodines, an imino ether intermediate is generated through mild iodane-mediated oxidation, facile N-internalization, and methoxy anion addition. This pivotal intermediate serves as a versatile platform capable of interception by a wide spectrum of nucleophiles, thereby enabling the generation of structurally diverse nitrogen heterocycles (>15 classes). …
