The sulfuric acid-catalysed reaction of 1,6-anhydro+D-glucopyranose in lbutanol at SO" gave butyl a-and P-D-glucopyranoside as the sole products. The initial kinetic alp ratio was 1.5, and the final a//3 ratio upon equilibration was 2.7. The four pseudo-first-order reaction rate constants involved h
