CH activation: The ruthenium‐catalyzed direct sp2 CH amidation of arenes by using sulfonyl azides as the amino source is presented (see scheme). A wide range of substrates were readily amidated including arenes bearing weakly coordinating groups. Synthetic utility of the thus obtained products was demonstrated in the preparation of biologically active heterocycles.
Ç ħ激活:所述的钌催化直接SP 2 ç ħ酰胺化,通过使用叠氮化物磺酰作为氨基源被呈现(参见方案)的芳烃。各种基材容易酰胺化,包括带有弱配位基团的芳烃。由此获得的产物的合成效用在生物活性杂环的制备中得到证明。
