✦ Synopsis
Efficient synthesis of both cis-and trans-3-azido-oxetane-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-b-amino acids into oligomers; the synthesis of a series of protected b-hexapeptides and the X-ray crystal structure of methyl 2,4-anhydro-6deoxy-5-O-benzyl-L-altronate are reported.
