The present invention provides 3- to 7-membered 1,3-diaza-4-oxo-heterocyclic derivatives, such as imidazolidinone O derivatives, capable of releasing in a controlled manner a biologically active aldehyde or ketone in the surrounding. The invention also relates to the use of these compounds as perfuming or flavoring ingredients, as well as to the perfuming compositions and consumer articles containing such derivatives. It also provides a process for preparing said derivatives of the invention

Imidazolidin-4-ones are suitable in practical applications as hydrolytically cleavable precursors for the controlled release of fragrant aldehydes and ketones. The corresponding profragrances were prepared by treating aliphatic carbonyl compounds with commercially available amino acid amines in the presence of a base to yield mixtures of diastereomers. The two diastereomers isolated from the reaction
