Starting from β-oxodithioesters and hydroxylamine, two completely different transformations afford either β-ketonitriles or isoxazoles with high chemoselectivity depending on the reaction conditions. The reaction of β-oxodithioesters with hydroxylamine in EtOH at room temperature in daylight gave β-ketonitriles in high yields. On the other hand, 3-methylthio-isoxazoles were efficiently obtained as the final products by heating the mixture of β-oxodithioesters and hydroxylamine in HOAc at 90 °C.
