ABSTRACT:
Compounds of the formulain which the dotted lines indicate the position of single or double bonds, R1represents a radical belonging to a fragrant alcohol of the formula R1OH, X represents a nucleophilic group selected from the group consisting of —OH, ═O, —NH2or —NHR3, R3representing a C1to C6straight-chain or branched hydrocarbon radical, saturated or unsaturated, or an aliphatic or aromatic ring having 5 or 6 carbon atoms, m and n define whole numbers within the range 0 to 2 such that the sum m+n is equal to 1 or 2, p defines a whole number with a value of 0 or 1, each of the symbols R2, R4, R5, R6, R7, taken independently, represents a hydrogen atom, a C1to C4straight-chain or branched hydrocarbon radical, saturated or unsaturated, optionally substituted and, taken two by two, they can form aromatic or aliphatic monocyclic, bicyclic or tricyclic substances with the carbon atoms to which they are bound, are compounds capable of releasing a fragrant alcohol of the formula R1OH upon hydrolysis of the ester bond.
