Cyclic compounds and their use as precursors of fragrant alcohols

摘要

Compounds of the formula in which the dotted lines indicate the position of single or double bonds, R₁ represents a radical belonging to a fragrant alcohol of the formula R₁OH, X represents a nucleophilic group selected from the group consisting of -OH, -O, -NH₂ or -NHR₃, R₃ representing a C₁ to C₆ straight-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 C₁ to C₄ straight-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.
