Application

3-Hydroxy-5-methylisoxazole can be used as a reactant to synthesize:
  • 3-Oxoisoxazole-2(3H)-carboxamides by reacting with dimethyl-carbamoyl chloride in the presence of potassium t-butoxide.
  • Hydroxymethyl-2-propen-1-yl-5-methyl-3(2H)-isoxazolone via ring-opening reaction with vinyl oxirane.
