  α-羟基膦酸二苄酯和α-羟基膦酸的绿色合成及细胞毒活性

  摘要：

  AbstractA series of dibenzyl α‐hydroxyphosphonates and the corresponding α‐hydroxyphosphonic acids, mostly new compounds, have been synthesized. The dibenzyl α‐hydroxyphosphonates have been obtained in the Pudovik reaction of substituted benzaldehydes and dibenzyl phosphite in the presence of triethylamine as the catalyst. The amount of the solvent was minimized during the reaction, and the workup involved crystallization from the reaction mixture. A new protocol was developed to transform the dibenzyl 1‐hydroxyphosphonates to the corresponding phosphonic acids by catalytic hydrogenation. The derivatives prepared were screened as potential cytotoxic agents against Mes‐Sa human uterine sarcoma cell line.

  Abstract New, green methods have been elaborated for the syntheses of α-hydroxyphosphonates and α-hydroxymethylenebisphosphonic derivatives (HMBPs, dronates). α-Hydroxyphosphonates were prepared via the Pudovik reaction, while the synthesis of HMBPs has been performed in the three-component reaction of carboxylic acids, phosphorus trichloride and phosphorus acid.

  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。

  A Nafion® resin‐supported oxovanadium(IV) catalyst was readily prepared via ion‐exchange method. This solid vanadyl perfluorinated sulfonate catalyst was used as an efficient and recoverable catalyst for the hydrophosphonylation of various aldehydes under solventless conditions at room temperature. The catalyst could be recovered by simple filtration and reused without a significant loss of activity
