  Oxetane cis- and trans β-amino-acid scaffolds from d-xylose by efficient SN2 reactions in oxetane rings: methyl and hydroxymethyl analogues of the antibiotic oxetin, an oxetane β-amino-acid

  摘要：

  Highly regioselective reactions of a benzylidene-protected oxetane with (i) triethylsilane-trifluoroacetic acid and (ii) Hanessian-Hullar bromination provide efficient access to 3-hydroxyoxetane carboxylates in which only the C-3 OH is unprotected. Subsequent nucleophilic displacements of the corresponding triflates by azide proceeds in consistently excellent yields without any elimination to provide syntheses of scaffolds for a range of methyl and hydroxymethyl analogues of the antibiotic oxetin, a naturally occurring oxetane cis-beta-amino acid.

  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.
