چکیده
The title compound, C(10)H(15)NO(7), consists of one methyl-enedi-oxy ring and two fused tetra-hydro-furan rings. The three fused rings exhibit cis arrangements at the ring junctions. One O atom of a tetra-hydro-furan ring and the H atoms bound to the neighboring C atoms are disordered over two orientations with site-occupancy factors of 0.69 (1) and 0.31 (1). intra-molecular O-H⋯O and C-H⋯O inter-actions stabilize the mol-ecular conformation. In the crystal structure, inter-molecular O-H⋯O and C-H⋯O inter-actions link the mol-ecules into a three-dimensional network.
