  Short oligomeric chains of C-glycosyl β-D-arabinofuranose configured tetrahydrofuran amino acids (where the C-2 and C-5 substituents of the tetrahydrofuran ring are cis to each other) exhibit a well-defined repeating turn secondary structure stabilised by (i, i − 2) inter-residue hydrogen bonds. This is in contrast to the epimeric α-D-arabinofuranose oligomer (where the C-2 and C-5 substituents of the tetrahydrofuran ring are trans to each other) in which there is no indication of any secondary structure in solution.

  C-糖基 β-D-阿拉伯呋喃糖配置的四氢呋喃氨基酸的短寡聚链（其中四氢呋喃环的 C-2 和 C-5 取代基彼此顺式）表现出明确的重复转角二级结构，通过（i ， 我 − 2) 残基间氢键。这与差向异构 α-D-阿拉伯呋喃糖低聚物（其中四氢呋喃环的 C-2 和 C-5 取代基彼此互为反式）相反，后者在溶液中没有任何二级结构的迹象。

  Infrared ion-dip spectroscopy coupled with DFT and ab initio calculations are used to establish the intrinsic conformational preference of the basic structural unit of a peptide mimic, a cis-tetrahydrofuran-based "carbopeptoid" (amide-sugar-amide), isolated at low temperature in the gas phase. The carbopeptoid units form a beta-turn-type structure, stabilized by an intramolecular NH -> OC hydrogen bond across the sugar ring, thus forming a 10-membered, C-10 turn. Despite the clear preference for C-10 beta-turn structures in the basic unit, however, the presence of multiple hydrogen-bond donating and accepting groups also generates a rich conformational landscape, and alternative structures may be populated in related molecules. Calculations on an extended, carbopeptoid dimer unit, which includes an alternating amide-sugar-amide-sugar-amide chain, identify conformers exhibiting alternative hydrogen-bonding arrangements that are somewhat more stable than the lowest-energy double beta-turn forming conformer.

  The multi-gram syntheses of two epimeric six-carbon tetrahydrofurancarboxylates based upon a D-arabinofuranose template are described. An approach to 3-O-benzyl protected derivatives is also detailed. Introduction of nitrogen at C-6 of these scaffolds leads to the generation of building blocks suitable for the generation of oligomers which possess well defined secondary structures. Radical bromination facilitates introduction of nitrogen at C-2, to afford anomeric α-amino acid derivatives which are elaborated to two unnatural diastereomers of the potent herbicidal natural product hydantocidin. X-Ray crystal structures of N-methyl-2-azido-2-deoxy-α-D-arabino-hex-2-ulofuranosonamide and N-dodecyl-2-azido-2-deoxy-β-D-arabino-hex-2-ulofuranosonamide are also disclosed.
