A one-pot iminium-ion-based strategy has been developed for the synthesis of structurally novel iminosugar-based hybrid molecules. Iminium ion derived from l-rhamnose lactol-mesylate reacted with electron-rich aromatic systems in an inter/intra molecular fashion to furnish pyrrolidine-based iminosugar C-aryl glycosides with a high degree of stereoselectivity. Iminium ion also reacted readily with active
