Pyranofuranones via Lewis Acid Mediated Hetero-Diels-Alder Reactions of 4-Furan-2(5H)-ones: A Convergent Route to the Manoalide Substructure

Abstract
A variety of dienes and 4-formylfuran-2(5H)-ones enter into hetero-Diels-Alder reactions. The choice of Lewis acid is decisive and must be tuned to the reactivity of both diene and dienophile. Sensitive cycloadducts are prepared in the presence of Me3Al/AlCl3 and a straightforward route to pyranofuranones is described.
