2,2,5,7,8-Pentamethylchroman-6-yl 2,3,4,6-tetra- O -acetyl-α- D -glucopyranoside from synchrotron data

The crystal structure of the title compound, C28H38O11, solved and refined against synchrotron diffraction data, contains two formula units in the asymmetric unit. In both molecules, the dihydropyran ring along with its methyl substituents is disordered and adopts two alternative half-chair conformations. The occupancy of the major conformers of the two molecules refined to 0.858 (5) and 0.523 (5).
