some of the methods are hampered by long reaction times, harsh conditions, and the need for catalysts that are not readily available. This work reports a novel method for dehydrogenation of N‐heterocycles. Specifically, O2.− generated in situ acts as the oxidant for N‐heterocycle substrates that are susceptible to oxidation through a hydrogen atom transfer mechanism. This method provides a general
在许多药物,天然产物和合成材料中都发现了含氮杂芳烃基序。尽管已经报道了几种通过相应的饱和杂环的脱氢合成这些化合物的优美方法,但是其中一些方法因反应时间长,苛刻的条件以及对催化剂的需求而难以获得。这项工作报告了一种新的N-杂环脱氢方法。具体而言,原位生成的O 2 .-充当N杂环底物的氧化剂,这些底物易受氢原子转移机制的氧化。这种方法为通向N-杂芳烃提供了一条通用的绿色路线。
