Availability of both diastereomers of 1-(-)-menthoxy-2,4-dimethyl-3,7-dioxo-2,4,6,8-tetraazabicyclooctane (5) through decarboxylative rearrangement of 5-(-)-menthoxy-1,3-dimethyl isouric acid (1) allowed the access to both enantiomers of 1,3-dimethylallantoin (6); circular dichroism spectra of the related homologues (-)-6a and (-)-allantoin proved their corresponding R-configurations.
