title: 1-(3-Hy-droxy-5,8-dimeth-oxy-4-methyl-1,2,3,4-tetra-hydro-1,4-ep-oxy-naphthalen-2-yl)ethan-1-one.
abstract: The stereochemistry and regioschemistry (exo) of the title compound, C15H18O5, were determined by the X-ray analysis. The meth-oxy groups essentially lie in the plane of the benzene ring to which they are attached, as described by the C-O-C C torsion angles of -176.80 (12) and 4.67 (19)°. In the crystal, O-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds link the mol-ecules, forming chains of R 2 (1)(8) rings along [010].
