Abstract

The title compound, C12H18N2O3, contains two fused five-membered rings; a nearly planar pyrrolidine ring, with a maximum deviation of 0.0352(11) Angstrom, and an oxazolidine ring in an envelope conformation. The average C=O distance of the pyrrolidine ketone groups is 1,210(2) Angstrom. The N-O distance in the oxadiazoline ring is 1.458 (2) Angstrom. The structure contains a spiro-cyclohexane group in a chair conformation.
