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. Such compounds are capable of releasing a fragrant alcohol of the formula R1OH upon hydrolysis of the ester bond.
该化合物的分子式为:其中虚线表示单键或双键的位置,R1代表属于具有R1OH分子式的芳香醇的基团,X代表从—OH、—NH2或—NHR3组成的亲核基团中选择的一个,其中R3代表C1至C6的直链或支链碳氢基团,饱和或不饱和,或者是具有5或6个碳原子的脂肪族或芳香环,m和n定义为0到2之间的整数,使得m+n等于1或2,p定义为值为0或1的整数,每个符号R2、R4、R5、R6、R7,独立地表示氢原子,或者是C1至C4的直链或支链碳氢基团,饱和或不饱和,可选地取代,两两结合时,它们可以与它们结合的碳原子形成芳香或脂肪环,形成单环、双环或三环物质。这些化合物能够在酯键水解时释放出R1OH分子式的芳香醇。
