reaction has been discovered, leading to the formation of α-(N-2-pyridonyl)ketones and heterocyclic analogues in good to excellent yields (14 examples, 48–90%). This reaction demonstrates the unusual use of a heterocyclic sp2 nitrogen nucleophile in a gold-catalyzed 6-endo-dig cyclization. The tandem process allows rapid access to α-(N-2-pyridonyl)ketones, making them a convenient building block for the synthesis
已经发现了一种新的Au(III)催化的串联胺化-水合反应,导致形成α-(N -2-吡啶基)酮和杂环类似物,产率高至优异(14例,48-90%)。该反应表明杂环sp 2氮亲核试剂在金催化的6- end - dig环化反应中的异常使用。串联过程允许快速获得α-(N -2-吡啶基)酮,这使其成为合成更复杂的N-烷基吡啶酮靶标的便捷组成部分。
