Abstract
Direct selective tosylation of benzyl α-D-xylopyranoside leads first to the 3-O-tosyl, then to the 2,3-di-O-tosyl derivative. The same procedure applied to benzyl β-D-arabinopyranoside leads first to the 2-O-tosyl then to the 2,3-di-O-tosyl derivatives. The ease of preparation and separation of these products offers a definite advantage over indirect methods that rely on the use of temporary masking groups.
