Annulation Reactions of Allenyl Esters: An Approach to Bicyclic Diones and Medium-Sized Rings

[Image: see text] A flexible approach to construct sterically congested bicyclo-alkenedione frameworks is reported. Under the action of potassium carbonate, α-sulphonyl cycloalkanones are added to functionalized allenyl esters, leading to a lactone intermediate that is subsequently reduced to initia...
