Abstract

A highly stereocontrolled 1,2-cis-α-glycosidation reaction under conditions mild enough for acid-labile alcohols has been developed using benzyl-protected glycopyranosyl diethyl phosphites as glycosyl donors in the presence of 2,6-di-tert-butylpyridinium iodide and tetrabutylammonium iodide.

We previously developed 1,2-cis-glycosidation with benzyl-protected glycopyranosyl phosphorodiamidimidothioates in the presence of 2,6-lutidinium toluene-p-sulfonate and Bu4NI, however, this method suffered from lengthy preparation of the glycosyl donors: S.
