  cis- and trans-3-Azido-oxetane-2-carboxylate scaffolds: hexamers of oxetane cis-β-amino acids

  摘要：

  Efficient synthesis of both cis- and trans-3-azido-oxktane-2-carboxylates relies upon efficient nucleophilic displacements of 3-O-triflates of oxetanes by trifluoroacetate and azide. Such structures are scaffolds for incorporation of oxetane-beta-amino acids into oligomers; the synthesis of a series of protected beta-hexapeptides and the X-ray crystal structure of methyl 2,4-anhydro-6-deoxy-5-O-benzyl-L-altronate are reported.

  An efficient multigram ring contraction of a 1,4-lactone 2-O-triflate derived from L-rhamnose-with retention of configuration in the ring closure-is the key step in the preparation of a series of oxetanes, which are pseudoenantiomeric analogues of the naturally occurring antibiotic oxetin, an oxetane cis-beta-amino acid. Subsequent nucleophilic displacements of the corresponding triflates by azide proceed in consistently excellent yields, without any elimination, to provide syntheses of scaffolds for analogues of the antibiotic.
