2,6-Dimethyl-4-oxocyclohexanecarboxylic acid: a meso keto acid

S. Xie, C. Kenny and P. D. Robinson

Abstract: The achiral meso title compound, C₉H₁₄O₃, is an intermediate for a series of structurally unique compounds. Intermolecular O-HO hydrogen bonds produce centrosymmetric R₂²(8) rings which dimerize the molecules through the carboxyl group, while C-HO interactions through the carboxyl -H atom and the ketone O atom interconnect the dimers via centrosymmetric R₄⁴(24) rings, producing infinite one-dimensional dimeric ribbons.
