Abstract Upon heating 3-aryl-S-phenyl-2(3H)-furanones (la-c) with benzylamine at 100°C in the absence of solvents, ring opening occurred with the formation of the corresponding N-benzylamides (3a-c). When the latter compounds (3a-c) were allowed to react with thionyl chloride at room temperature, the corresponding isothiazolones (4a-c) were obtained. Treatment of the isothiazolones (4a-c) with sodium
