An unprecedented Pd-catalyzed decarboxylative coupling reaction of aromatic carboxylic acids in aqueous medium under air: synthesis of 3-aryl-imidazo[1,2-a]pyridines from aryl chlorides
An efficient and practical protocol for palladium-catalyzeddecarboxylative arylation of imidazo[1,2-a]pyridine-3-carboxylic acids with aryl chlorides has been developed. Note that the reaction could proceed smoothly without an additive in aqueous medium under an ambient atmosphere, and the addition of H2O could effectively promote the decarboxylative arylation. Particularly noteworthy is that these
已开发出一种有效,实用的方案,用于钯催化的咪唑并[1,2 - a ]吡啶-3-羧酸与芳基氯化物的脱羧芳基化反应。注意,在环境气氛下在水性介质中没有添加剂的情况下反应可以顺利进行,并且H 2 O的添加可以有效地促进脱羧芳基化。特别值得注意的是,这些结果代表了Pd催化的(杂)芳香族羧酸在水性介质中在空气中的P催化脱羧偶联反应的第一个实例,以及3-芳基-咪唑并[1,2- a]合成的第一个成功实例。吡啶使用廉价的各种芳基氯化物和杂芳基氯化物作为起始原料。
Design, synthesis and biological activity of N-(2-phenoxy)ethyl imidazo[1,2-a]pyridine-3-carboxamides as new antitubercular agents
A series of N-(2-phenoxy)ethyl imidazo[1,2-a]pyridine-3-carboxamides (IPAs), based on the structure of WZY02 discovered in our lab, were designed and synthesized as new anti-TB agents. Results reveal that many of them exhibit excellent in vitro inhibitory activity with low nanomolar MIC values against both drug-sensitive MTB strain H37Rv and drug-resistant clinical isolates. Compounds 15b and 15d display
根据在我们实验室中发现的WZY02的结构,设计并合成了一系列N-(2-苯氧基)乙基咪唑并[1,2 - a ]吡啶-3-甲酰胺(IPAs),作为新型抗结核药物。结果表明,它们中的许多对药物敏感性MTB菌株H37Rv和耐药性临床分离株均表现出优异的体外抑制活性,且纳摩尔摩尔MIC值低。化合物15b和15d显示出良好的安全性和药代动力学特征,表明它们有望成为未来抗结核药物发现的先导化合物。
