Abstract: In the title compound, C17H18O4, the heterocyclic ring has a half-chair conformation. The substituents at the 3- and 4-positions are attached equatorially with respect to the heterocyclic ring. The molecules are linked by O-H...O hydrogen bonds, the hydroxyl O atom functioning as both donor and acceptor. This results in the formation of C(2) chains running along the twofold screw axis.
