Abstract

A facile and practical one-pot synthesis of β-oxo thio­amides from β-oxo amides has been developed. By treatment with isothiocyanates in ethanol in the presence of potassium carbonate, a series of β-oxo amides was converted, under reflux, in high yields into the corresponding β-oxo thioamides.
