Abstract

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 been demonstrated.
