Crystal structure of (±)-(5SR,6SR)-6-ethenyl-1-[(RS)-1-phenylethoxy]-1-azaspiro[4.5]decan-2-one

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...

Description
Summary: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 R22(16) ring motif. The dimers are linked by a second pair of C—H...O interactions, enclosing an R42(12) ring motif, into a tape structure along the b axis.
