An efficient and high-yielding strategy to prepare "unsymmetrical" 4-aryl-isoxazol-3,5-dicarboxylic acid derivatives from nitroacetic esters and aromatic aldehydes has been developed. The strategy is based on the isolation and usage of the previously missed intermediate of the Dornow reaction-5-hydroxy-6-oxo-4-aryl-6-1,2-oxazine-3-carboxylates. In addition, the mechanism of the Dornow reaction was partially revised.
已经开发出一种从硝基乙酸酯和芳香醛制备“不对称”4-芳基异噁唑-3,5-二羧酸衍生物的高效高产策略。该策略基于多诺反应中先前错过的中间体 5-羟基-6-氧代-4-芳基-6-1,2-噁嗪-3-羧酸酯的分离和使用。此外，还部分修订了多诺反应的机理。
