as a solvent (without any cosolvent) promotes the aza-Michael reaction of diethyl vinylphosphonate and diphenylvinylphosphine oxide with a wide range of N-nucleophiles. The solubility of the starting phosphorus substrate in water does not play a crucial role in the reaction course, decreasing to some extent the reaction rate. The reaction can be performed either at room temperature or under reflux to
摘要 使用水作为溶剂(没有任何助溶剂)促进了乙烯基膦酸二乙酯和二苯基乙烯基氧化膦与多种 N-亲核试剂的氮杂-迈克尔反应。起始磷底物在水中的溶解度在反应过程中不起关键作用,在一定程度上降低了反应速率。该反应可以在室温或回流下进行,以通过简单的冷冻干燥分离程序以优异的产率和高纯度提供相应的 β-氨基膦酸酯和 β-氨基膦氧化物。碱性催化剂的应用使得弱亲核试剂如α-氨基酸及其磷类似物的添加成为可能;即α-氨基膦酸。
