REACTION OF N-(3-OXOALKENYL)CHLOROACETAMIDES WITH SODIUM p-TOLUENESULFINATE – SYNTHESIS OF 3-TOSYLPYRIDIN-2(1Н)-ONES

Abstract

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.
