Anionic Diels-Alder chemistry of electron-deficient cross-conjugated vinylogous alkenones, providing highly stable sodium dienolate ion pairs as electron-rich dienes in the presence of a weak sodium base in THF, has been newly developed, leading to a single Diels-Alder adduct, in racemic form, in moderate to high yields (up to 97%, 37 examples).

The syntheses of several neovibsanin derivatives were carried out in order to elucidate the simple structure required for displaying neurite outgrowth activity. In addition, a fluorescent probe molecule was synthesized and the analysis of its behavior in the PC12 cell line showed that the neovibsanins accumulate on the outer edge of the cell at the site of formation of prominences.

A full account of the preparation, reactivity, and spectral properties of three 1,3-dioxin vinylogous esters (4-6) is presented.The synthetic approach of these versatile β-ketovinyl cation equivalents involves a BF3*Et2O-promoted Prins reaction between cyclic 1,3-diketones (i.e., 1,3-cyclopentanedione, 1,3-cyclohexanedione, and 1,3-cycloheptanedione) and either formaldehyde or trioxane.The reactions explored include reductive and alkylative 1,3-ketone transpositions, affording a variety of simple β-unsubstituted and β-substituted α-hydroxymethyl α,β-enones, alkylations with carbon electrophiles, and hydroxylations with oxygen electrophiles.
