Ethyl 2-{[2-(2-ethoxy-2-oxoethoxy)quinolin-4-yl]carbonyloxy}acetate

Abstract

The conformation of the 2-ethoxy-2-oxoethoxy side chain, including a gauche Ce—O—C—C3 [72.46 (16)°] (e = ethoxy) unit, in the title compound, C18H19NO7, is partly determined by an intramolecular C—H...O hydrogen bond. In the crystal, C—H...O hydrogen bonds and C—H...π interactions arising from the same methylene group form chains extending along the a-axis direction.
