  “Backdoor Induction” of Chirality: Asymmetric Hydrogenation with Rhodium(I) Complexes of Triphenylphosphane-Substituted β-Turn Mimetics

  摘要：

  Bioconjugate bidentate ligands 2-10 were obtained by tethering triphenylphosphanecarboxylic acid to amino acid substituted spacers with different flexibility, ranging from a rigid enediyne-based beta-turn inducer to flexible linear aliphatic chains with up to eight carbon atoms. The 21 synthesized ligands revealed up to 81% ee selectivity in rhodium-catalyzed asymmetric hydrogenation of alpha,beta-unsaturated amino acids. The key feature of the catalysts is the prochiral coordination sphere of the catalytic metal while the chirality is transmitted by "backdoor induction" from distant hydrogen-bonded amino acids. DFT calculations were applied to study the structure and relative stability of the precatalytic organometallic Rh(I) complexes, with particular emphasis on hydrogen-bonded secondary structures.

• Self-Assembly of Small Peptidomimetic Cyclophanes

  DOI：10.1002/chem.200400031

  日期：2004.8.20

  The self-assembly of a series of small peptidomimetic cyclophanes in organic solvents was studied. X-ray diffraction, NMR spectroscopy, and molecular modelling were used to understand the structural features of these self-assembling compounds both at the molecular and supramolecular level. The factors that could influence the formation of gels rather than crystals were studied and a model for the arrangement

  研究了一系列小拟肽环烷在有机溶剂中的自组装。使用X射线衍射，NMR光谱和分子模型来了解这些自组装化合物在分子和超分子水平上的结构特征。研究了可能影响凝胶而不是晶体形成的因素，并提出了分子在凝胶中排列的模型。此外，扫描电子显微镜显示，在某些情况下，这些化合物在从有机胶凝剂转变为螺旋状凝胶纤维时会经历手性的转录。

  Amphiphilic amino acid derived compounds are very interesting for the design of building blocks able to self-assemble into highly ordered nanostructures, in a hierarchical and controlled fashion. With this aim, the modular synthesis and the full characterization of simple Gemini Amphiphilic Pseudopeptides (GAPs) have been carried out. These compounds were designed to establish intermolecular interactions

  两亲氨基酸衍生的化合物对于能够以分层和受控方式自组装成高度有序的纳米结构的构件的设计非常有趣。为了这个目的，已经进行了简单的双子双亲两性伪肽（GAP）的模块合成和完整表征。这些化合物被设计为以层级方式建立分子间的相互作用，以最终使超分子组装成为有序的纳米结构，例如纤维，管，带或球形囊泡。已经实现了不同的结构变量，例如氨基酸侧链，中央间隔区的长度和疏水尾的性质。此外，通过在不同极性的溶剂中进行研究，系统地检查了环境的影响（氯仿， 甲醇 或水性 甲醇）和不同的pH值（中性，碱性和酸性）。已经在固体（SEM，TEM和FT-IR）以及溶液状态（NMR，UV，CD，FT-IR和荧光光谱）中研究了GAP的非共价自组装能力和结构特征。此外，通过监视ATR FT-IR对溶剂的缓慢蒸发，已经建立了溶液与固态之间的联系。这项研究已经允许在GAP的化学结构与其形成纳米结构的能力之间建立关系。在某些最佳情况下（尤
