Abstract

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.
