  Dihedral angle restriction within a peptide-based tertiary alcohol kinetic resolution catalyst

  摘要：

  Kinetic resolution of several tertiary alcohols has been evaluated with a peptide-based catalyst that was designed to probe the role of dihedral angle restrictions for certain bonds within the catalyst. In particular, the nucleophilic residue (pi-Me)-His has been replaced with the (beta-Me)-(pi-Me)-His. A synthesis of the key residue is presented, along with characterization data that suggests the substituent exerts a substantial ground state conformational effect. In addition, kinetic resolution data indicate that the H- to Me-substitution confers enhanced stereoselectivity in several tertiary alcohol resolutions. (c) 2006 Elsevier Ltd. All rights reserved.

  Asymmetric Azidation−Cycloaddition with Open-Chain Peptide-Based Catalysts. A Sequential Enantioselective Route to Triazoles

  摘要：

  A family of beta-substituted histidine-containing peptides has been synthesized to probe the effect of noncovalent conformational rigidification on catalyst enantioselectivity. Unambiguous enhancement of enantioselectivity in the conjugate addition of azide to alpha,beta-unsaturated carboxylate derivatives has been achieved, enabling application to a sequential asymmetric azidation/cycloaddition for the synthesis of optically enriched triazoles and triazolines.
