Copper-Catalyzed Synthesis of Purine-Fused Polycyclics
摘要:
A novel protocol for a Cu-catalyzed direct C-(sp2)-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.
