Abstract

An efficient, metal-free, NBS-mediated thiocyanation protocol has been developed for the synthesis of (6-(hydroxyimino)-2-thiocyanatocyclohex-1-en-1-yl)(phenyl)methanone derivatives from cyclohexene-fused isoxazoline N-oxides under mild conditions. This rapid, one-pot transformation is achieved in acetonitrile, and provides access to diverse SCN-containing compounds bearing a wide range of functional groups in good to excellent yields. Moreover, an SCN containing product was further utilized for the synthesis of cyclohexanone ring-fused isothiazole derivatives.
