  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 Lewis acid catalyst has been first applied to the hydrophosphonylation of ketones, giving the corresponding quaternary α-hydroxy phosphonates in high yields (up to 98%). The present method was highly tolerable for functionalized ketones. Moreover, the first catalytic enantioselective hydrophosphonylation of an unactivated ketone was also realized by using a tridentate Schiff base-titanium complex

  路易斯酸催化剂已首先应用于酮的氢膦酰化反应，从而以高收率（高达98％）得到相应的季α-羟基膦酸酯。本方法对于官能化的酮具有高度的耐受性。此外，还通过使用三齿席夫碱-钛络合物实现了未活化的酮的第一催化对映体选择性氢膦酰基化。

  A highly efficient and mild [bmIm]OH-catalyzed a-hydroxylation of phosphonates using O-2 as the oxygen source is described. The employment of ionic liquid under mild reaction conditions makes this transformation green and practical. Especially, this reaction provided a novel and convenient methodology for the construction of quaternary a-hydroxy phosphonates.
