Abstract: The relative configuration of the title molecule, C₇H₁₀O₃, has been determined. The asymmetric C atoms are of opposite chirality (R,S or S,R), as opposed to having the same chirality (R,R or S,S). The molecule adopts an antiperiplanar conformation around the bond connecting the cyclopropyl and carbonyl groups. In the crystal structure, molecules form hydrogen-bonded chains.
