  General Synthesis of Unsymmetrical Norbornane Scaffolds as Inducers for Hydrogen Bond Interactions in Peptides^,

  摘要：

  Starting from readily accessible endo-cis-(2S,3R)-norbornene dicarboxylic acid benzyl monoester, a general and efficient synthetic approach toward unsymmetrical two-stranded peptidic structures was developed. In these structures the peptide strands are oriented in a parallel geometry. Their synthesis is easily applicable to a variety of amino acids and peptides. Specifically, a norbornane template as molecular scaffold induces hydrogen bonding between the adjacent peptide strands. The specific hydrogen bonding patterns between these strands were revealed by detailed NMR analysis including TOCSY/NOE experiments.
