Abstract The reaction of 5(4H)-pyrazolone with phosphorus ylides afforded new triphenylphosphanylidene alkanone derivatives. Moreover, its benzylidene derivative reacted with Wittig–Horner reagents to give the corresponding dialkoxyphosphoryl, alkyl phosphonate, and heterocyclic products. Treatment of pyrazole-4-carbaldehyde with Wittig–Horner reagents and trialkyl phosphites gave the respective alkyl
摘要 5(4H)-吡唑啉酮与磷叶立德反应生成了新的三苯基亚膦基烷酮衍生物。此外,其亚苄基衍生物与 Wittig-Horner 试剂反应生成相应的二烷氧基磷酰基、烷基膦酸酯和杂环产物。用 Wittig-Horner 试剂和亚磷酸三烷基酯处理 pyrazole-4-carbaldehyde,得到相应的烷基膦酸酯加合物。讨论了新产品形成的机制。还检查了一些新合成化合物的生物活性。图形概要
