We report a Cu(II)-catalyzed C–H amidation/cyclization of azomethine imines with dioxazolones as acyl nitrene transfer reagents under additive- and ligand-free conditions. An array of 1,2,4-triazolo[1,5-a]pyridine derivatives were afforded in moderate to good yields with excellent functional group tolerance. In addition, scale-up reaction and photoluminescence properties were discussed.
我们报告了在无添加剂和无配体条件下,Cu(II) 催化的 C-H 酰胺化/环化偶氮甲碱亚胺与二恶唑酮作为酰基氮烯转移试剂。一系列 1,2,4-三唑并[1,5- a ] 吡啶衍生物以中等至良好的产率提供,具有优异的官能团耐受性。此外,还讨论了放大反应和光致发光特性。

The present disclosure provides compounds having the general structure A or pharmaceutically acceptable salts thereof:
R—X (A)
wherein R is an alkyl or aryl moiety comprising heterocyclic structures; and X is a metal-chelatin group selected from:
This disclosure further provides a focused library of compounds for use in the discovery and design of metallo-enzyme inhibitors. This fragment-based approach provides an assembly of a library of low molecular weight compounds (MW<300 Da) containing a variety of potential metal-chelating groups. The identification of the inhibitory scaffolds among these compounds provides the initial hit fragments that may be optimized for affinity against a particular target using common medicinal chemistry, structure-based or NMR-based approaches.
