Abstract
In the title compound, C11H19NO5, the five-membered pyrrolidine ring adopts an envelope conformation. The dihedral angles between the carboxyl group plane, the pyrrolidine ring and the methoxy group are 59.50 (3) and 62.02 (1)°, respectively. In the crystal, intermolecular O—H⋯O hydrogen bonds link the molecules into chains along [100]. The absolute configuration is assigned in accord with that of (2R,4R)-1-(tert-butoxycarbonyl)-4-hydroxypyrrolidine-2-carboxylic acid, which was the starting material in the synthesis.
