An efficient method for the synthesis of 4-sulfenyl isoxazoles has been developed via AlCl3-mediated electrophiliccyclization/sulfenylation of 2-alkyn-1-one O-methyloximes. Remarkably, N-arylsulfanylsuccinimides are employed as electrophiles for the construction of 4-arylsulfanyl isoxazoles, and 4-alkylsulfanyl isoxazoles are accessed with dialkyl disulfides as electrophiles.
