✦ Synopsis

In the title compound, C~10~H~15~NO~3~, the central six-membered ring has a chair conformation. The conformations of the fused furan and oxopyrrolidine rings are close to envelopes. Molecules form chains parallel to the a axis via O—H...O intermolecular hydrogen bonds, which help to stabilize the crystal structure.
