In this study, Michaelis-Arbuzov-type reaction of 1-imidoalkyltriarylphosphonium salts with phosphites, phosphonites, and phosphinites was used in the synthesis of a wide range of phosphorus analogs of α-amino acids such as 1-imidoalkylphosphonates, 1-imidoalkylphosphinates, and 1-imidoalkylphosphine oxides. Large differences were observed in the reactivity of substrates depending on their structure
在本研究中,1-亚氨基烷基三芳基鏻盐与亚磷酸酯、亚膦酸酯和亚膦酸酯的 Michaelis-Arbuzov 型反应被用于合成各种 α-氨基酸的磷类似物,例如 1-亚氨基烷基膦酸酯、1-亚氨基烷基膦酸酯和1-亚氨基烷基氧化膦。在底物的反应性中观察到很大差异,这取决于它们的结构,尤其是鏻部分和 N 保护基团的类型。已经开发了可以以良好到极好的收率获得预期产品的条件。已经提供了转换的机械方面。
