1-O-Acetyl-3,4,6-tri-O-benzyl-2-C-bromo­methyl-2-de­oxy-α-D-glucopyran­ose

In the 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 a weak intra­molecular C—H...O hydrogen bond.

The mol­ecule of the title compound, C₁₁H₈O₃, is essentially planar [r.m.s. deviation = 0.025 (2) Å]. In the crystal, mol­ecules are stacked along [110] but no short π–π contacts are observed. Weak C—H...O inter­actions link the mol­ecules into chains along [101].
