  Expeditious preparation of isoxazoles from Δ2-isoxazolines as advanced intermediates for functional materials

  摘要：

  A collection of isoxazoles derivatives has been efficiently synthesized in three steps. The oximation reaction of aldehydes followed by nitrile oxide [3+2] 1,3-dipolar cycloaddition and MnO2-oxidation reaction furnished the title compounds which were purified by simple filtration on celite (R).

  The palladium catalyzed one-pot synthesis of isoxazoles and pyrazoles from aryl iodides, terminal alkynes, chromium hexacarbonyl and hydroxylamine hydrochloride or aqueous hydrazine solution is described. The Sonogashira carbonylative coupling intermediate was trapped in situ by hydroxylamine hydrochloride or aqueous hydrazine to deliver isoxazoles or pyrazoles, respectively, in high yields. This efficient

  描述了由芳基碘化物，末端炔烃，六羰基铬和羟胺盐酸盐或肼水溶液以钯催化一锅合成异恶唑和吡唑的方法。Sonogashira羰基偶联中间体被羟胺盐酸盐或肼水溶液原位捕获，分别以高收率递送异恶唑或吡唑。这种有效的方法在大气压和中等温度下进行，不需要使用铜，膦配体或气态一氧化碳。
