Abstract

In the title compound, C19H25NO2, the pyrrolidine ring adopts an envelope form, with the spiro C atom as the flap, while the cyclohexane ring shows a chair form. A weak intramolecular C - H⋯O interaction supports the molecular conformation, generating an S(6) ring motif. In the crystal, pairs of C - H⋯O interactions connect the molecules into inversion dimers with an R 2 2(16) ring motif. The dimers are linked by a second pair of C - H⋯O interactions, enclosing an R 4 2(12) ring motif, into a tape structure along the b axis.
