3-Formylphenyl-2,3,4,6-tetra-O-acetyl-α-<scp>D</scp>-glucopyranoside

The title compound, C21H24O11, crystallizes exclusively as the α-anomer. The 3-formyl&#173;phenyl substituent at C1 is in the axial position, whereas all other groups are in equatorial positions. As a consequence, the re-face of the aldehyde group is somewhat shielded by the C6 acetyl group.
