1-Azetines, 1,2-Thiazetin-1,1-dioxides and Isothiazol-1,1-dioxides as Building Blocks in Heterocyclic Synthesis: the Attempted Synthesis of Bicyclic β-Sultams

This thesis is concerned with the synthesis of β-sultams and the development of new routes for the synthesis of bicyclic versions of these molecules as potential anti-bacterials.
