The convenient regioselective scalable synthesis of 3,4-diaryl-5-carboxy-4,5-dihydroisoxazole 2-oxides was developed based on a condensation of simple starting materials (arylbenzaldehydes, arylnitromethanes, and ethoxycarbonylmethylpyridinium bromide) under mild conditions. The obtained synthons can be applied for the synthesis of 3,4-diarylisoxazole derivatives capable of suppressing malignant growth
基于简单的起始原料(芳基苯甲醛,芳基硝基甲烷和乙氧基羰基甲基溴化吡啶)在温和条件下的缩合,开发了方便的区域选择性可扩展的3,4-二芳基-5-羧基-4,5-二氢异恶唑2-氧化物的合成方法。所获得的合成子可用于合成能够抑制恶性生长的3,4-二芳基异恶唑衍生物。
