Bicyclic amino acids derived from the natural sugars D-arabinofuranose and D-fructofuranose have been synthesised; their ability to induce a turn conformation in peptides has been exploited in the preparation of a cyclic RGD loop mimetic.
and tricyclic compounds were synthesized starting from fructose. The different hydroxyl groups present in fructose were exploited in the formation of a number of conformationally constrained sugar-based scaffolds, including azido acids. Introduction of an azido group and carboxy terminus into different bicyclic iodo ethers, allowed the synthesis of different conformationally constrained azido acids.
