4-Formyl-phenyl 2,3,4,6-tetra-O-acetyl-?-d-allopyran-oside.


ABSTRACT: The title compound, C(21)H(24)O(11), crystallizes exclusively as the ?-anomer. The substituent of the protected sugar at position C-3 is in the axial position, while all other groups are in equatorial positions. The pyran-oside ring adopts a stable chair conformation.
