A series of N-(3-oxoalkenyl)chloroacetamides was prepared by acylation of β-enaminoketones with chloroacetyl chloride. A reaction of these compounds with sodium p-toluenesulfinate in dimethylformamide in the presence of potassium carbonate led to 3-tosylpyridin-2(1H)-ones. The limitations of this reaction were studied.
