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.
通过用氯乙酰氯将β-烯酮酮酰化来制备一系列N-(3-氧代烯基)氯乙酰胺。在碳酸钾存在下,这些化合物与对甲苯磺酸钠在二甲基甲酰胺中的反应生成3-甲苯磺酰吡啶-2(1 H)-one 。研究了该反应的局限性。
