1. An aromatic derivative having the formula (I) or the salt thereof:
wherein R1 and R2 independently represent a hydrogen atom, hydroxyl, a halogen atom, or OR3 wherein R3 is C1-C10 alkyl; A-B represents a hydrocarbon moiety having 1 to 10 carbon atoms and containing at least one double bond or a sulfur-or oxygen-containing hydrocarbon moiety having 1 to 10 carbon atoms; n is an integer of 2 to 4; X represents a group
NH-; and Y represents a hydrogen atom; alkyl having 1 to 5 carbon atomswhich may be substituted with aryl; alkenyl having 2 to 5 carbon atoms which may be substituted with aryl or aryl substituted with at least one C1-C5 alkoxy; aryl which may be substituted with at least one carboxy or C1-C5 alkoxycarbonyl or C1-C5 alkoxy; provided that, when R1 and R2 are both hydrogen, the moiety -A-B-(CH2)n-X-Y does not represent -CH = CH
(CH2)n-COOR4 wherein n = 2 to 4 and R4 is hydrogen or C1-C5 alkyl.
1.具有式(I)的芳香族衍生物或其盐:
其中 R1 和 R2 独立地代表氢原子、羟基、卤素原子或 OR3,其中 R3 是 C1-C10 烷基;A-B 代表具有 1 至 10 个碳原子并含有至少一个双键的烃基或具有 1 至 10 个碳原子的含硫或含氧的烃基;n 是 2 至 4 的整数;X 代表基团
NH-;Y 代表氢原子;具有 1 至 5 个碳原子的烷基,可被芳基取代;具有 2 至 5 个碳原子的烯基,可被芳基取代或被至少一个 C1-C5 烷氧基取代的芳基;可被至少一个羧基或 C1-C5 烷氧基羰基或 C1-C5 烷氧基取代的芳基;但当 R1 和 R2 均为氢时,分子 -A-B-(CH2)n-X-Y 不代表 -CH = CH
