  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。

  Whereas trimers and tetramers of beta-C-D-arabinofuranosyl carbohydrate amino acids adopt well defined conformations based around a repealing beta-turn like structure, stabilised by (i, i-2) inter-residue hydrogen bonds, there is no indication of any secondary structure in the tetramer of the epimeric alpha-C-D-arabinoluranosyl carbohydrate amino acid, where the C-2 and C-5 substituents of the tetrahydrofuran ring are Irans to each other.

  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.

  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.
