A method of protecting benzaldehyde carbonyl groups during metal- ammonia reductions by intermediate conversion into the N,N?- dimethylimidazolidine by reaction with N,N?-dimethylethylenediamine, has been exemplified by conversion of 4-isopropyl-benzaldehyde into its 2,5-dihydro derivative. This is a principal flavouring matter of cumin seeds.
