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