A novel protocol for a Cu-catalyzed direct C((sp(2)))-H activation/intramolecular amination reaction of 6-anilinopurine nucleosides has been developed. This approach provides a new access to a variety of multiheterocyclic compounds from purine compounds via Cu-catalyzed intramolecular N-H bond tautomerism which are endowed with fluorescence.
一种新型的铜催化 6-苯胺基嘌呤核苷的 C((sp(2)))-H 直接活化/分子内胺化反应的方案已经被开发出来。该方法通过铜催化的分子内 N-H 键互变异构作用,从嘌呤化合物中提供了一种新的途径来获得多种多杂环化合物,这些化合物具有荧光性质。
