A series of structurally diverse unsaturated sugar-derived lactones has been prepared. α,β-Butenolides were introduced to the sugar moiety starting from epoxides, while α-methylene-γ-lactones were constructed from a carbonyl precursor, either an aldehyde, a ketone or a lactone. In the last case, an unprecedented Reformatsky-type reaction has been developed.
