    摘要:
    该发明提供了化合物和方法,例如,用于催化贝氏碱衍生物对环状约束硝基乙烯化合物进行醛的有机催化Michael加成,从而提供环状约束的α-取代-γ-硝基醛。当使用手性吡咯烷催化剂时,反应可以实现对映选择性,从而以几乎光学纯形式(例如,96%至>99% e.e.)获得Michael加合物。Michael加合物可以在羰基相邻处携带单取代基或双取代基。Michael加合物可以高效转化为环状约束的保护γ-氨基酸残基,这对于γ-肽折叠体系的系统构象研究至关重要。还提供了制备其他γ-氨基酸和肽的新方法。这些新的构建模块可用于制备折叠体,例如α/γ-肽折叠体,在溶液中和固态中采用特定螺旋构象。

  • Organocatalytic Asymmetric Conjugate Additions to Cyclopent‐1‐enecarbaldehyde: A Critical Assessment of Organocatalytic Approaches towards the Telaprevir Bicyclic Core

    In the context of a programme directed at the manufacture of telaprevir, eight possible approaches to its bicyclic α‐amino acid core, based on organocatalytic enantioselective conjugate additions to cyclopent1enecarbaldehyde, were identified and preliminarily explored. Four reactions, delivering advanced intermediates en route to the target amino acid, were selected for a thorough optimisation. Three
    在针对telaprevir的生产计划的背景下,基于对环戊-1-烯甲醛的有机催化对映选择性共轭加成反应,确定并初步探索了八种可能的双环α-氨基酸核心途径。为了全面优化,选择了四个反应,这些反应在向目标氨基酸的途中提供了先进的中间体。此反应中的三个涉及用脯醇催化剂(添加硝基甲烷,硝基乙酸盐和乙酰氨基丙酸盐)进行亚胺离子催化,一个基于鸡纳衍生的相转移催化剂(添加甘亚胺)。在某些情况下,精心选择添加剂可将催化剂负载量降低至0.5 mol%。通过利用现成的底物和催化剂,制备能够以高收率和对映选择性接近特拉匹韦的核心的中间体,突显了有机催化技术在经济高效地制备药物方面的潜力。
  • Evaluation of a Cyclopentane-Based γ-Amino Acid for the Ability to Promote α/γ-Peptide Secondary Structure

    We report the asymmetric synthesis of the gamma-amino acid (1R,2R)-2-aminomethyl-1-cyclopentane carboxylic acid (AMCP) and an evaluation of this residue's potential to promote secondary structure in alpha/gamma-peptides. Simulated annealing calculations using NMR-derived distance restraints obtained for alpha/gamma-peptides in chloroform reveal that AMCP-containing oligomers are conformationally flexible. However, additional evidence suggests that an internally hydrogen-bonded helical conformation is partially populated in solution. From these data, we propose characteristic NOE patterns for the formation of the alpha/gamma-peptide 12/10-helix and discuss the apparent conformational frustration of AMCP-containing oligomers.

    The invention provides compounds and methods, for example, to carry out organocatalytic Michael additions of aldehydes to cyclically constrained nitroethylene compounds catalyzed by a proline derivative to provide cyclically constrained α-substituted-γ-nitro-aldehydes. The reaction can be rendered enantioselective when a chiral pyrrolidine catalyst is used, allowing for Michael adducts in nearly optically pure form (e.g., 96 to >99% e.e.). The Michael adducts can bear a single substituent or dual substituents adjacent to the carbonyl. The Michael adducts can be efficiently converted to cyclically constrained protected γ-amino acid residues, which are essential for systematic conformational studies of γ-peptide foldamers. New methods are also provided to prepare other γ-amino acids and peptides. These new building blocks can be used to prepare foldamers, such as α/γ-peptide foldamers, that adopt specific helical conformations in solution and in the solid state.
