biologically significant 5-aroyl 1,2,4-oxadiazole scaffolds using aryl methyl ketones and amidoximes. The strategy produces structurally diverse 5-aroyl 1,2,4-oxadiazoles in good to excellent yields, with a broad substrate scope that includes drug derived substrates. The reaction proceeds through iodine/DMSO-mediated oxidation of aryl methyl ketones, followed by imine formation and subsequent cyclization to
开发了一种无金属、碘催化的方案,用于使用芳基甲基酮和偕胺肟构建具有生物学意义的 5-芳酰基 1,2,4-恶二唑支架。该策略可产生结构多样的 5-芳酰基 1,2,4-恶二唑,产率良好至优异,底物范围广泛,包括药物衍生底物。该反应通过碘/DMSO 介导的芳基甲基酮氧化进行,随后形成亚胺并随后环化以产生所需产物。此外,该方案还成功生产了 ataluren 和 tioxazafen 的羰基类似物,并促进了一些有趣的后期转化。
