  酰基膦酸酯与有机铝试剂的反应：合成仲和叔α-羟基膦酸酯的新方法

  摘要：

  报道了有机铝试剂（三甲基铝，三乙基铝等）与芳基和烷基酰基膦酸酯的反应，导致以中等至良好的产率形成α-羟基膦酸酯。根据反应条件，该方法可轻松获得仲和叔α-羟基膦酸酯。三乙基铝与一系列酰基膦酸酯在0°C的反应生成仲α-羟基膦酸酯，而在-100°C时，它们生成叔α-羟基膦酸酯。

  日期：——

  A highly efficient Cu-catalyzed direct hydroxylation of phosphonate compounds has been developed. This transformation provides a powerful method for the synthesis of quaternary α-hydroxy phosphonates in good yields. The direct transformation process, regiospecific selectivity, and good tolerance to a variety of substituents make it an alternative approach to the reported protocols.

  A new, environmentally benign, convenient, and easy method of synthesizing tertiary -hydroxyphosphonates by the triethylamine-catalyzed hydrophosphonylation of unactivated ketones was developed. In the presence of triethylamine, aromatic or heteroaromatic ketones can react with phosphite to form tertiary -hydroxyphosphonates under solvent-free and mild conditions. The proposed method was also suitable for functionalized ketones.

This method provides easy access to secondary and tertiary α-hydroxy phosphonates depending on the reaction conditions. The reactions of triethylaluminum with a series of acyl phosphonates at 0 °C gave the secondary α-hydroxy phosphonates, while at −100 °C they afford
