1-[2,4,6-Trimethyl-3,5-bis-(4-oxopiperidin-1-ylmeth-yl)benz-yl] piperidin-4-one

Abstract

In the structure of the title compound, C27H39N 3O3, each of the (4-oxopiperidin-1-yl)methyl residues adopts a flattened chair conformation (with the N and carbonyl groups being oriented to either side of the central C4 plane) and they occupy positions approximately orthogonal to the central benzene ring [Cbenzene - C - Cmethyl-ene - N torsion angles 103.4 (2), -104.4 (3) and 71.9 (3)°]; further, two of these residues are oriented to one side of the central benzene ring with the third to the other side. In the crystal packing, supra-molecular layers in the ab plane are sustained by C - H⋯O inter-actions.
