A Selectfluor and base mediated protocol for the synthesis of cyclohexanone ring fused isoxazole derivatives from isoxazoline N-oxides has been successfully developed. This rapid, one-pot, two-step transformation is achieved in acetonitrile, through nitroso intermediate followed by hydration, defluorination and N–O coupling in the presence of triethylamine. The scope and mechanism of the protocol have
从异恶唑啉N-氧化物合成环己酮环稠合的异恶唑衍生物的Selectfluor和碱介导的方案已成功开发。这种快速,一锅,两步的转化是在乙腈中,通过亚硝基中间体,然后在三乙胺存在下进行水合,脱氟和N-O偶联来实现的。该协议的范围和机制已得到证明。
