A cationic cobalt(III)‐catalyzed direct CH amidation of unactivated (hetero)arenes and alkenes by using 1,4,2‐dioxazol‐5‐ones as the amidating reagent has been developed. This transformation proceeds efficiently under external oxidant‐free conditions with a broad substrate scope. Moreover, 6‐arylpurine compounds, which often exhibit high potency in antimycobacterial, cytostatic, and anti‐HCV activities
阳离子钴(III)催化的直接Ç 者H已被开发未活化的(杂)芳烃和烯烃通过使用-1,4,2-二恶唑-5-酮作为酰胺化试剂的酰胺化。这种转化在广泛的底物范围内,在无外部氧化剂的条件下有效进行。此外,通常在抗分枝杆菌,细胞生长抑制和抗HCV活性方面表现出高功效的6-芳基嘌呤化合物可以被平滑地酰胺化,从而为它们的后期功能化提供了温和的方案。
