  Enantioselective synthesis of α-hydroxy phosphonates via oxidation with (camphorsulfonyl)oxaziridines

  摘要：

  Reaction of phosphonate anions with enantiomerically pure (camphorsulfonyl)oxaziridines results in formation of nonracemic alpha-hydroxy phosphonates. This enantioselective hydroxylation methodology provides convenient access to optically active alpha-hydroxy phosphonates and their corresponding phosphonic acids. (C) 1997 Elsevier Science Ltd.

  serve as an efficient catalyst for hydrophosphonylation of aldehydes and aldimines, giving the corresponding alpha-hydroxy and alpha-amino phosphonates with high enantioselectivity, respectively. The scope of the hydrophosphonylation was wide, and both aliphatic and aromatic aldehydes and aldimines were successfully used as substrates for the reaction. The potent catalysis of the complex is attributed to

  以模块化合成方式新合成了光学活性铝（salalen）配合物2，发现它可作为醛和醛亚胺氢膦酰化的有效催化剂，分别得到相应的具有高对映选择性的α-羟基和α-氨基膦酸酯. 氢膦酰化的范围很广，脂肪族和芳香族醛和醛亚胺都成功地用作反应的底物。该复合物的强大催化作用归因于其独特的结构：它采用扭曲的三角双锥体构型，这使得 salalen 配体呈顺式-β 样结构，其中手性氨基位于靠近金属中心的位置。

  our results concerning the first squaramide-catalysed hydrophosphonylation of aldehydes. In all cases, the reactions proceeded smoothly and cleanly under mild reaction conditions rendering final α-hydroxy phosphonates in very good yields and high enantioselectivities. It is one of the few organocatalytic examples of this reaction using aldehydes. It is the first time that diphenylphosphite (1e) has

  我们报告有关醛的第一个方胺催化的氢膦酰化反应的结果。在所有情况下，反应均在温和的反应条件下平稳而干净地进行，从而以非常好的收率和高对映选择性产生最终的α-羟基膦酸酯。它是使用醛的该反应的少数有机催化实例之一。与先前公开的方法中使用的亚磷酸二烷基酯相反，这是首次将亚磷酸二苯基酯（1e）成功用于醛的手性Pudovik反应中，从而扩大了这种不对称方法的通用性。
