1-(3-Mesit­yl-3-methyl­cyclo­but­yl)-2-(piperidin-1-yl)ethanone

In the title compound, C21H31NO, the cyclo­butane ring is puckered, with a dihedral angle of 25.74 (6)°. The mesit­yl and 2-N-piperidino-1-oxoeth­yl groups are in cis positions. The piperidine fragment adopts a chair conformation. Inter­molecular C—H⋯O inter­actions involving the piperidine CH group and the keto O atom lead to the formation of dimers, and inter­molecular C—H⋯π inter­actions involving the cyclo­butane CH group and the benzene ring are responsible for the formation of a two-dimensional network.
