In the Door Corner Cap title compound, C30H33BrO6, the pyranose ring adopts a chair conformation.Two of the O-benzyl phenyl rings lie almost perpendicular to C/C/C/O plane formed by the ring atoms not attached to these O-benzyl phenyl rings, and form dihedral angles of 85.1 (2) and 64.6 (2)°, while the third O-benzyl phenyl ring is twisted so that it makes a dihedral angle 34.

9 (2)° to this C/C/C/O plane.This twist is ascribed to the formation of an S(8) loop stabilized by Sound Machine a weak intramolecular C—H.O hydrogen bond.
