  Catalytic Hydrogenation of Chiral α-Amino and α-Hydroxy Esters at Room Temperature with Nishimura Catalyst without Racemization

  摘要：

  The hydrogenation or carboxylic acid derivatives at room temperature was investigated. With a mixed Rh/Pt oxide (Nishimura catalyst), low to medium activity was observed for various alpha-amino and alpha-hydroxy esters. At 100 bar hydrogen pressure and 10% catalysts loading, high yields or tire desired amino alcohols and diols were obtained without racemization. The most suitable alpha-substituents were NH2, NHR, and 011, whereas beta-NH2 were less effective. Usually, aromatic rings were also hydrogenated, but with the free bases of amino acids as substrates, some selectivity was observed. No reaction was round for alpha-NR2, alpha-OR, and unfunctionalized esters; acids and amides, were also not reduced under these conditions. A working hypothesis for the mode or action of the catalyst is presented.

  摘要：

  通过悬浮共聚反应合成了一种由氯化血红素、二乙烯基苯和2-甲基-5-乙烯基吡啶组成的新型高分子试剂。伯、仲和叔烷基卤与氯化血红素共聚物与氰化物、叠氮化物和硫氰酸根离子的取代反应得到了令人满意的产率。根据立体化学研究，该反应机理被揭示为 SNi 型。氯化血红素共聚物不仅是具有功能性的聚合物负载试剂，而且还用于将产物与反应混合物分离。

  The synthesis of hydroxamic acids starting from carboxylic acids employing 1-propanephosphonic acid cyclic anhydride (T3P) activation is described. Application of ultrasonication accelerates this conversion. Further, the T3P has also been employed to activate the hydroxamates, leading to isocyanates via the Lossen rearrangement. The isocyanates were trapped with suitable nucleophiles to afford the

  inhibition of polo-like kinase 1 (PLK1) and BRD4 bromodomain by a single molecule could lead to the development of an effective therapeutic strategy for a variety of diseases in which PLK1 and BRD4 are implicated. Compound 23 has been found to be a potent dual kinase-bromodomain inhibitor (BRD4-BD1 IC50 = 28 nM, PLK1 IC50 = 40 nM). Compound 6 was found to be the most selective PLK1 inhibitor over BRD4
