The efficient asymmetricsynthesis of the antifungal pyrrolidine alkaloid (+)-preussin (2) was accomplished via the stereoselective reduction of a 5-substituted 3-oxo proline. The oxo proline was prepared from an N-sulfinyl δ-amino β-ketoester, a sulfinimine derived polyfunctionalized chiral building block.
