  Secondary structure of homo-thiopeptides based on a bridged β-proline analogue: preferred formation of extended strand structures with trans-thioamide bonds

  摘要：

  Homo-thiopeptides of bicyclic 7-azabicyclo[2.2.1]heptane-2-endo-carboxylic acid (Ah2c), which is a conformationally constrained beta-proline mimic, were synthesized and their structures were investigated. These homo-thiopeptides showed a preference for ordered secondary structures with trans-thioamide bonds in the solid state and in solution. (C) 2012 Elsevier Ltd. All rights reserved.
