✦ Synopsis
The chiral title compound, C 8 H 9 NO 4 , crystallizes in the noncentrosymmetric space group P2 1 2 1 2 1 , but in the absence of an atom with significant anomalous dispersion, the absolute configuration could not be determined. The H atoms in both methyl groups are eclipsed with respect to the C O bond. The structure features weak C-HÁ Á ÁO interactions that link the molecules into a three-dimensional network.

In the crystal structure of the title compound, C 14 H 17 NO 3 , intermolecular O-HÁ Á ÁO hydrogen bonds [OÁ Á ÁO = 2.692 (4) A ˚] link the molecules into extended one-dimensional chains. These chains are, in turn, linked into a threedimensional network by weak intermolecular C-HÁ Á ÁO interactions
In the title molecule, C 12 H 10 O 4 , the lactone and benzene rings are coplanar, while the plane of the acetyl substituent is rotated by 12.26 (9) from the molecular plane. The molecules stack throughinteractions along [100] and these stacks are laterally connected by C-HÁ Á ÁO hydrogen bonds alon
