Environmentally benign β-stereoselective glycosidations of glycosyl phosphites using a reusable heterogeneous solid acid, montmorillonite K-10 Original Research Article

Environmentally benign and stereoselective β-glycosidations of glycopyranosyl phosphites and alcohols using a reusable heterogeneous solid acid, montmorillonite K-10, as an activator have been developed. By these glycosidations, β-gluco-, 2-deoxy-β-gluco-, and β-mannopyranosides were selectively produced in good to high yields.
