  Oxetane cis- and trans-β-amino-acid scaffolds from l-rhamnose by efficient SN2 reactions in oxetane rings; pseudoenantiomeric analogues of the antibiotic oxetin

  摘要：

  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.

  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.
