Abstract
In the title compound, C17H19NO8 [systematic name = dimethyl 4-hydroxy-4-methyl-2-(3-nitrophenyl)-6-oxocyclohexane-1,3-dicarboxylate], the cyclohexanone ring exhibits a chair conformation. The methoxycarbonyl groups are oriented in opposite directions with respect to the cyclohexanone ring. In the crystal, O—H⋯O hydrogen bonds links the molecules into chains running parallel to the a axis. These chains are connected by weak C—H⋯O hydrogen bonds, forming sheets parallel to the ab plane.
