General description

3-Aminoisoxazole (isoxazol-3-amine) is a 3-substituted isoxazole derivative. It is a structural isomer of 5-aminoisoxazole.

Application

3-Aminoisoxazole (isoxazol-3-amine) may be used in the following studies:
  • As a reagent in the synthesis of N-(4-(N-isoxazol-3-ylsulfamoyl)phenyl)acetamide.
  • As a starting material in the synthesis of N-(isoxazol-3-yl)-N′-(carbomethoxy)thiourea.
  • As a starting material in the synthesis of (Z)-2-(5-amino-1,2,4-thiadiazol-3-yl)-2-methoxy-iminoacetic acid, a side-chain of the fourth generation of cephem antibiotics.
