  Helix-Forming Carbohydrate Amino Acids

  摘要：

  [GRAPHICS]The solution-phase conformational properties of tetrameric and octameric chains of C-glycosyl alpha-D-lyxofuranose configured tetrahydrofuran amino acids (where the C-2 and C-5 substituents on the tetrahydrofuran ring are trans to each other) were examined using NMR and IR and CD in organic solvents. Studies by NMR and IR demonstrated that in chloroform solution, the tetramer 7 does not adopt a hydrogen-bonded conformation whereas the octamer 10 populates a well-defined helical secondary structure stabilized by 16-membered (i, i - 3) interresidue hydrogen bonds, similar to a pi-helix. Circular dichroism studies in trifluoroethanol are consistent with this conformation for the octamer 10, and also indicate that the tetramer 7 adopts a rigid conformation not stabilized by hydrogen bonds.

  From sequencamers to foldamers? Tetrameric furanose carbopeptoids from cis- and trans-5-aminomethyl-tetrahydrofuran-2-carboxylates

  摘要：

  The synthesis of three stereoisomeric cis- and trans-5-azidomelhyl-tetrahydrofuran-2-carboxylates in which a ketal-protected cis-diol unit is present is described. The monomers undergo efficient oligomerisation to tetrameric carbopeptoids in which the diol protection facilitates ready purification by chromatography which augurs well for the formation of homogeneous higher polymers.
