Polyfunctional pyrazoles 6.* Convenient method for the synthesis of 1-aryl-1H-pyrazole-3,4-dicarboxylic acids
摘要:
A preparatively convenient method was developed for the synthesis of 1-aryl-1H-pyrazole-3,4-di-carboxylic acids based on the alkaline hydrolysis and oxidation of 1-aryl-4-formyl-1H-pyrazole-3-carboxylic esters with hydrogen peroxide in an aqueous medium.
