title: 2,2,5,7,8-Penta-methyl-chroman-6-yl 2,3,4,6-tetra-O-acetyl-α-d-glucopyran-oside from synchrotron data.
abstract: The crystal structure of the title compound, C(28)H(38)O(11), solved and refined against synchrotron diffraction data, contains two formula units in the asymmetric unit. In both mol-ecules, the dihydro-pyran ring along with its methyl substituents is disordered and adopts two alternative half-chair conformations. The occupancy of the major conformers of the two mol-ecules refined to 0.858 (5) and 0.523 (5).
