Chemistry of Dioxenium Cations. Synthetic and Mechanistic Studies on the Stereocontrolled Formation of Tetrahydropyrans from Homoallylic Alcohols and Ortho Esters

Despite their long history, dioxenium cations are underutilized reactive synthetic intermediates.It was found that ortho esters and homoallylic alcohols in the presence of Lewis acids provide 4-heterosubstituted pyranosides in a stereoselective manner.The

Chemistry of aldolate dianions. β-silyloxy silyl enol ethers as bifunctional nucleophilic equivalents for oxygen heterocycle synthesis

A variety of β-silyloxy silyl enol ethers (3) are easily produced by double deprotonation of readily available β-hydroxyketones. These substances undergo cyclization reactions with dioxenium cations to provide 2-alkoxy-tetrahydropyranones, thus confirming the use of 3 as bifunctional reagents for oxygen heterocycle synthesis.
