Description
Synthesis Analysis
The synthesis of isoxazole-4-carboxylic acid derivatives, including 5-methyl-3-phenylisoxazole-4-carboxylic acid, has been achieved through innovative methods. A notable approach involves the domino isoxazole-isoxazole isomerization, catalyzed by Fe(II), leading to isoxazole-4-carboxylic esters and amides with good yields. This process showcases a controlled transformation of 4-acyl-5-methoxy-/5-aminoisoxazoles into desired products under specific conditions .
