    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.
