  3-Aza-8,10-dioxa-bicyclo[5.2.1]decane (9-exo BTKa) carboxylic acid as a new reverse turn inducer: synthesis and conformational analysis of a model peptide

  摘要：

  Dipeptide isostere 5, belonging to the class of 9-exo BTKa, was synthesised starting from R,R-tartaric acid and 4-nitro-1-(3-nitrophenyl)butan-1-one. The nine-membered lactam showed interesting structural features and was inserted in a 5-residue model peptide. The conformational properties of this modified peptide have been Studied by NMR and molecular modelling, indicating that Compound 5 acted as it reverse turn inducer. (c) 2005 Elsevier Ltd.
