First Synthesis and Structure of Ethyl 3,3,5,5-Tetracyano-2-hydroxy-2-methyl-4,6-diphenylcyclohexane-1-carboxylate

Ethyl 3,3,5,5-tetracyano-2-hydroxy-2-methyl-4,6-diphenylcyclohexane-1-carboxylate was synthesized for the first time by three-component condensation of benzaldehyde with ethyl acetoacetate and malononitrile in the presence of trichloroacetic acid. The product structure was proved by X-ray analysis.
