摘要

建立了一种温和、简便的用碘基苯氧化醛肟生成氧化腈的方法。在氧化过程中，通过相应的腈氧化物二聚化反应，醛肟几乎定量地转化为呋喃嘧啶。在烯烃和炔双极亲和试剂的存在下进行氧化，得到收率较高的异恶唑或异恶唑。

A Convenient Method of Generation of Nitrile Oxides by Iodosylbenzene and Its Reaction.

A mild and convenient method for generation of nitrile oxide is established by iodosylbenzene oxidation of aldehyde oximes. Aldehyde oximes were converted to furoxans in almost quantitative yields via dimerization of corresponding nitrile oxides upon oxidation. When the oxidation was carried out in the presence of alkene and alkyne dipolarophiles, isoxazolines or isoxazoles were obtained in good yields.
