  利用自然界的结构多样性：开发用于钌催化的酮的对映选择性转移氢化的模块化二肽类似物配体。

  摘要：

  基于叔丁氧羰基（N-Boc）-保护的α-氨基酸和手性邻位氨基醇的组合，制备了新颖的二肽-类似物配体的文库。这些高度模块化的配体与[[RuCl（2）（p-cymene）]（2）]结合，并筛选得到的金属配合物作为催化剂，用于在转移氢化条件下使用2-丙醇作为氢供体的对苯乙酮对映选择性还原。用几种新颖的催化剂可获得极好的1-苯基乙醇对映体选择性（ee高达98％）。尽管大多数配体包含两个立体中心，但已证明产物醇的绝对构型是由配体的氨基酸部分的构型决定的。利用基于L-氨基酸的配体生成S-构型产物，基于D-氨基酸的催化剂有利于R-构型醇的形成。N-Boc-L-丙氨酸和（R）-苯基甘醇（Boc-L-Ab）或其对映异构体（N-Boc-D-丙氨酸和（S）-苯基甘醇，Boc-D-Aa）的组合被证明是还原过程的最佳配体。评估了许多芳基烷基酮的转移氢化反应，并获得了极佳的对映选择性，最高可达96％ee。

• Design and preparation of serine–threonine protein phosphatase inhibitors based upon the nodularin and microcystin toxin structures: Part 2.1 Synthesis of a functionalised nodularin macrocycle and a stripped-down microcystin macrocycle
  作者：Antony B. Maude、Amit P. Mehrotra、David Gani

  DOI：10.1039/a702410j

  日期：——

  Nodularins and microcystins are complex natural isopeptidic hepatotoxins that serve as subnanomolar inhibitors of the eukaryotic serine–threonine protein phosphatases, PP1 and PP2A. In Part 1 (A. P. Mehrotra, K. L. Webster and D. Gani, J. Chem. Soc., Perkin Trans. 1, 1997, preceding paper) each of the key structural or potentially reactive motifs within each macrocycle type was assessed as a contributor towards phosphatase inhibitory efficacy and a stripped-down nodularin-type macrocycle was identified as a suitable precursor to potentially active synthetic inhibitors. Subsequently, synthetic routes to the 19-membered nodularin macrocyclic system were developed, using solution-phase chemistry, which demonstrated that only certain cyclisation protocols were viable. Here we describe an extension of this chemistry to provide a 19-membered nodularin macrocycle, cyclo-[(3R)-3-hydroxymethyl-β-Ala-( R)-Glu-α-OMe-γ-Sar-(R)-Asp- α-OMe-β-(S)-Phe-], appropriately functionalised with a hydroxymethyl group for the incorporation of lipophilic side-chains. We also demonstrate that the 25-membered microcystin macrocycle, cyclo-[β-Ala-(R)-Glu-α- OMe-γ-Sar-(R)-Ala-(S)-Leu-( R)-Asp-α-OMe-β-(S)- Phe-], can be prepared in good yield using similar protocols in which macrocyclisation is effected through the reaction of the amino group of the (2S)-phenylalanine residue with the β-pentafluorophenyl ester of the (2R)-aspartic acid residue.

  结节素和微囊藻毒素是复杂的天然同型肽肝毒素，作为真核丝氨酸-苏氨酸蛋白磷酸酶PP1和PP2A的亚纳摩尔抑制剂。在第一部分（A. P. Mehrotra, K. L. Webster和D. Gani，《化学学会杂志》，珀金斯1号，1997年，前面的论文）中，评估了每种大环类型中每个关键结构或潜在反应性基序对磷酸酶抑制效力的贡献，并确定了一个简化版的结节素型大环作为潜在活性合成抑制剂的合适前体。随后，开发了使用溶液相化学合成19元结节素大环体系的合成路线，这表明只有某些环化方案是可行的。在这里，我们描述了这种化学方法的扩展，以提供一个19元结节素大环，环状-[(3R)-3-羟甲基-β-Ala-(R)-Glu-α-OMe-γ-Sar-(R)-Asp-α-OMe-β-(S)-Phe-]，适当地带有羟甲基团以纳入亲脂性侧链。我们还证明了25元微囊藻毒素大环，环状-[β-Ala-(R)-Glu-α-OMe-γ-Sar-(R)-Ala-(S)-Leu-(R)-Asp-α-OMe-β-(S)-Phe-]，可以使用类似的方案以良好产率制备，其中大环化是通过(2S)-苯丙氨酸残基的氨基与(2R)-天冬氨酸残基的β-五氟苯酯的反应实现的。

Following coupling of N-protected α-amino acids with N-substituted β-amino acid tert-butyl esters, that affords linear α,β-dipeptides, the protecting groups at the terminal functionalities were removed and the open-chain dipeptides were cyclized with phenylphosphonic dichloride, PhP(O)Cl2, to give the desired cyclic α,β-dipeptides

  A series of amino acid prodrugs of racemic and chiral 7-(3-amino-1-pyrrolidinyl)-6-fluoro-1,8-naphthyridine-3-carboxylic acids, 1-cyclopropyl-6,8-difluoro-3-quinolinecarboxylic acids, 1-cyclopropyl-6-fluoro-3-quinolinecarboxylic acids, and 5-amino-1-cyclopropyl-6,8-difluoro-3-quinolinecarboxylic acids have been prepared and evaluated for comparative antibacterial activity. Compounds were prepared by acylation of the 3-amino group of the pyrrolidine with common amino acids using standard peptide chemistry. This series has been compared with the parent compounds for antibacterial activity in vitro and in vivo as well as for comparatively solubility. The amino acid analogues were less active in vitro, but had equal or increased efficacy in vivo. Indeed, it was proven that these compounds, which were stable to acid and base under the reaction conditions for their preparation, were rapidly cleaved in serum to give the parent quinolones. The amino acid derivatives showed a 3-70 times improved solubility when compared to the parent compounds. The most active compound of the series was [S-(R*,R*)]-7-[3-[2-amino-1-oxopropyl)-amino]-1-pyrrolidinyl]-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid (PD 131112).
