Azetidine Iminosugars from the Cyclization of 3,5-Di-<i>O</i>-triflates of α-Furanosides and of 2,4-Di-<i>O</i>-triflates of β-Pyranosides Derived from Glucose

Abstract

Primary amines with either 3,5-di-<i>O</i>-ditriflates of α-furanosides or 2,4-di-<i>O</i>-triflates of β-pyranosides form bicyclic azetidines in high yield
