Structure of (1R, 5R)-l-p-menth-3-yloxy-2, 4-dimethyl-cis-2, 4, 6, 8-tetraazabicyclo[3.3.0]octane-3, 7-dione.

The asymmetric unit contains two independent molecules. The title compound is the first example of a derivative of the bicyclol tautomer in the allantoin series and the key intermediate in the asymmetric synthesis of the X-ray structure determination confirm its diastereomeric identity and establish the absolute (1R, 5R) configuration.
