An efficient method for the synthesis of nojirimycin- and pyrrolidine-based iminosugar derivatives has been developed. The strategy is based on the partial reduction in sugar-derived lactams by Schwartz’s reagent and tandem stereoselective nucleoph

The photoexcited N-vinylazetidinones could undergo a ring expansion by a [1,3]-acyl shift to afford 2,3-dihydro-4-pyridones. A modular set-up was used for the studies in flow, with remote real-time control of the reaction course via UV-Vis.
