α/β-Stereo- and diastereoselective glycosylation with n-pentenyl glycoside donors, promoted by N-iodosuccinimide and catalyzed by chiral Brønsted acid

Abstract

A new chiral Brønsted acid catalyst, the (+)-isomenthol ester of pentacarbomethoxycyclopentadiene, combined with N-iodosuccinimide promote stereo- and diastereoselective glycosylation with n-pentenyl glycoside donors.
