COMPOUNDS FOR A CONTROLLED RELEASE OF ACTIVE PERFUMING MOLECULES

摘要

The present invention relates to the field of perfumery. More particularly, it concerns compounds comprising at least one beta-thio carbonyl or nitrile moiety capable of liberating an active molecule selected from an alpha,beta-unsaturated ketone, aldehyde or nitrile. The present invention concerns also the use of said compounds in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds. (I) wherein: a) m represents an integer from 1 to 6; b) Pro represents a hydrogen atom or a group susceptible of generating an odoriferous alpha,beta-unsaturated ketone, aldehyde or nitrile and is represented by the formulae (II) or (II') in which the wavy line indicates the location of the bond between said Pro and the sulfur atom S; and at least one of the Pro groups is of the formula (II) or (II').
