Abstract
A facile and convergent approach has been developed for the stereoselective construction of biologically important polyhydroxylated 2-acyl indolizidine framework using aza-Cope rearrangement-Mannich cyclization as a key step. The generality of this methodology is demonstrated with various lactol-tosylates derived from carbohydrates. The presented method provides an easy access to indolizidine- and tetrahydroindolizine-based iminosugar derivatives in good yields.
