Optimized synthesis of aroyl-S,N-ketene acetals by omission of solubilizing alcohol cosolvents
Aroyl-S,N-ketene acetals are obtained by condensation of aroyl chlorides and 2-methyl-N-benzylbenzothiazolium salts in 1,4-dioxane at room temperature in short reaction time in 20–99% yield. This protocol represents a considerable improvement over the standard synthesis in 1,4-dioxane/ethanol mixtur...

| Summary: | Aroyl-S,N-ketene acetals are obtained by condensation of aroyl chlorides and 2-methyl-N-benzylbenzothiazolium salts in 1,4-dioxane at room temperature in short reaction time in 20–99% yield. This protocol represents a considerable improvement over the standard synthesis in 1,4-dioxane/ethanol mixtures at elevated temperatures. |
