Abstract
The title compound, C9H11NO3, was prepared by an Aldol reaction of 2,3-dihydro-1H-pyrrolizin-1-one with formaldehyde. The asymmetric unit contains six molecules. The pyrrolizine ring system in each molecule is planar, the maximum atomic deviation being 0.066 (2) Å. In the crystal structure, molecules are liked together by an extensive O—H⋯O hydrogen-bonding network.
