Article abstract of DOI:10.1021/jo00021a043

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
