Reaction of arylpropargyl aldehydes with 2,3-dihydroxylamino-2,3-dimethylbutane results in the formation of 2-(1-hydroxy-4,4,5,5-tetramethylimidazolidin-2-ylidene)-1-arylethanones in high yields (70-80%). Allowing availability of propargyl aldehydes, this method gives new possibilities for the preparation of 2-(1-hydroxy-4,4,5,5-tetramethylimidazolidin-2-ylidene)-1-arylethanones.
