The present invention relates to the field of perfumery. More particularly, it concerns compounds comprising at least one β-thio carbonyl or nitrile moiety capable of liberating an active molecule selected from an α,β-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 α,β-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').
本发明涉及香料领域。更具体地,涉及包含至少一个β-硫代羰基或硫代腈基团的化合物,能够释放所选的α,β-不饱和酮,醛或腈活性分子。本发明还涉及在香料中使用所述化合物,以及包含本发明化合物的调香组合物或香料制品。(I)其中:a) m代表1到6之间的整数;b) Pro代表氢原子或能够产生具有气味的α,β-不饱和酮,醛或腈的基团,并由式(II)或(II')表示,其中波浪线表示Pro与硫原子S之间的键的位置;并且至少一个Pro基团为式(II)或(II')。
