PERFUME PRECURSOR

PROBLEM TO BE SOLVED: To provide a perfume precursor that has excellent storage stability, particularly in an aqueous product, and allows the long-term sustained-release of a flavor, and a method for producing the same, a perfuming method using the same, a flavor composition comprising the same, and a fiber treatment agent, cosmetics, hair cosmetics, and a detergent comprising the flavor composition. SOLUTION: A perfume precursor comprises an ester of a flavor having a phenol structure or a hydroxy-4-pyrone structure, and an aliphatic dicarboxylic acid having carbon atoms of 6 or more and 20 or less.

Esters derived from vanillin and vanillal and aromatic and functionalized aliphatic carboxylic acids

Reactions of vanillin and vanillal with aromatic and functionally substituted aliphatic carboxylic acid chlorides in the presence of pyridine afforded the corresponding previously unknown esters.
