【 摘 要 】

In the title compound, C12H15IO7, the 3,4-di­hydro-2H-pyran ring is in a distorted half-boat conformation with the atom bearing the acet­yloxy group adjacent to the C atom bearing the methyl­acetate group lying 0.633 (6) Å above the plane of the remaining ring atoms (r.m.s. deviation = 0.0907 Å). In the crystal, mol­ecules are linked into a supra­molecular chain along the a axis through two C—H⋯O inter­actions to the same acceptor carbonyl O atom; these chains pack with no specific inter­molecular inter­actions between them.
