Abstract: Described herein are compounds of formula (I) as properfume compounds, as well as a method to release a compound being a carbonyl of formula (II), a formate ester of formula (III) and/or an alcohol of formula (IV), by exposing the compound of formula (I) to an environment wherein it is oxidized. Also described herein are a perfuming composition and a perfume consumer product including at least one compound of formula (I).

Abstract: The present invention relates to compounds of formula (I) as properfume compounds. In particular, the present invention relates to a method to release a compound being a ketone or aldehyde of formula (II), a formate ester of formula (III) and/or an alcohol of formula (IV) by exposing the compound of formula (I) to an environment wherein it is oxidized. Moreover, the present invention relates to a perfuming composition and a perfume consumer product comprising at least one compound of formula (I).

Abstract: Precursor or pro-fragrance compounds used as a precursor to deliver at least one fragrant compound that is capable of imparting an odor, in particular one which imparts an odor to a material, more particularly to a fabric or textile. The pro-fragrant compounds of the invention include fragrant alcohols (R1OH) released from a compound of Formula I or in which Formula I is derived from (R1OH) and encompass any fragrant alcohol having more than three carbon atoms. Also, methods of generating the fragrant compounds and to improve, enhance or modify odoriferous properties of a perfuming composition or a perfumed article are also disclosed, as are the resultant perfuming compositions and articles.

Abstract: A compound is provided of Formula (I) wherein R1 represents a C3 to C20 hydrocarbon group derived from an alcohol of formula R1OH, from a formate of formula R1OCH?O, or a cinnamyl aldehyde of Formula (II) wherein a compound of Formula I is capable of releasing a compound, when oxidized, selected from the group consisting of a fragrant alcohol of formula R1OH, a fragrant formate ester of formula R1OCH?O and aryl aldehyde of Formula (III) wherein R2 is, independently, hydrogen atom, hydroxyl group, optionally substituted C1-C6 alkyl group, C1-C6 alkoxy group, or —O(C?O)CH(CH3)2 wherein any two of R2 may form an optionally substituted 5 or 6 membered ring. The compounds are useful for example as a precursor for the prolonged delivery or release of fragrant compounds such as fragrant alcohols, fragrant aldehydes or fragrant formates.
