[EN] IMIDAZOPYRIDINES AS A NOVEL SCAFFOLD FOR MULTI-TARGETED KINASE INHIBITION [FR] IMIDAZOPYRIDINES UTILISÉES COMME NOUVEL ÉCHAFAUDAGE POUR L'INHIBITION DES KINASES À CIBLES MULTIPLES
本文介绍了CuX介导的2-苯基咪唑并[1,2- a ]吡啶在氧气存在下的区域选择性卤化反应。该反应为生产C-3卤代2-苯基咪唑并[1,2- a ]吡啶提供了一种有效的方法,收率高达96%。提出了一种通过 2-苯基咪唑并[1,2- a ]吡啶-CuX 络合物中间体形成标题化合物的合理机制。代表性化合物的结构是通过单晶XRD方法建立的。通过 Hirshfeld 表面分析和 DFT 计算证实的电子结构合理化了相关吸收和发射的特征以及大的斯托克斯位移。

A facile method for the synthesis of 3-iodoimidazo[1,2-a]pyridines has been successfully developed involving an I2O5-mediated iodocyclization cascade of N-(1-arylallyl)pyridin-2-amines with concomitant C═Cbondcleavage. Preliminary mechanistic studies reveal that this protocol might undergo an oxidative cyclization/decarboxylation/iodination sequence in which I2O5 is used as both an oxidant and an
已成功开发了一种简便的合成3-碘咪唑并[1,2- a ]吡啶的方法,该方法涉及I 2 O 5介导的N-(1-芳基烯丙基)吡啶-2-胺与C═C的碘环化级联反应键断裂。初步的机理研究表明,该方案可能会经历氧化环化/脱羧/碘化过程,其中I 2 O 5既用作氧化剂,又用作碘源。本协议具有衬底范围广,操作简单和无金属条件的优点。
