corresponding α,α-(1 → 1) and α,β-(1 → 1) disaccharides. Hence, pure 2,3,4,6,2′,3′,4′,6 - octa-O-benzyl derivatives of α,α-trehalose, and the d -galacto and d -manno analogues were obtained, after column chromatography, in 55–65% yield. Hydrogenolysis gave the corresponding free sugars. The pure anomers were obtained in 10–34% yield. The potentiality of the method was demonstrated by the synthesis of 2,3
