An agent for influencing plant growth, in particular a herbicidal and plant growth inhibiting agent, contains, in addition to carriers and/or other additives, at least one compound of the formula:-
or the corresponding zwitterion form in which R and R1 may be the same or different and each can be hydrogen, deuterium or an optionally substituted lower alkyl group, lower alkenyl, lower alkynyl, cycloalkyl, aryl or heterocyclic radical containing one or more oxygen, nitrogen or sulphur atoms and which may be fused to an aromatic ring, a lower alkyl group substituted by a cycloalkyl radical, a lower alkyl group substituted by an aryl radical, a lower alkyl group substituted by a heterocyclic radical as defined above, or R and R together form a polymethylene chain optionally interrupted by an oxygen, nitrogen or sulphur atoms, or R represents, together with the C(R)-N < residue to which it is attached, the atoms required to complete a heterocyclic radical; and R2 and R3 may be the same or different and each can be hydrogen, optionally substituted lower alkyl, cycloalkyl, aryl or lower alkyl substituted by a heterocyclic radical containing one or more nitrogen atom; a heterocyclic radical containing one or more nitrogen atoms; or R2 and R3, independently, together with the C(H)-N residue to which each is attached, may each represent the atoms required to complete a heterocyclic radical; R. is OH CH3; or phenyl; R7 is hydrogen or an alkoxycarbonyl or benzyloxycarbonyl group; and n is 0, 1, 2 or 3; as well as the esters or partial esters thereof with physiologically splittable alcohols; salts of the compounds of formula I, or their esters or partial esters with acids or bases physiologically acceptable to plants, respectively; and all optical isomers thereof.

或相应的齐聚物形式,其中 R 和 R1 可以相同或不同,并且各自可以是氢、氘或任选取代的低级烷基、低级烯基、低级炔基、环烷基、芳基或杂环基,这些基团含有一个或多个氧原子、氮原子或硫原子,并可与芳香环融合;被环烷基取代的低级烷基、被芳基取代的低级烷基、被上文定义的杂环基取代的低级烷基,或 R 和 R 共同形成可选择被氧、氮或硫原子打断的多亚甲基链,或 R 与所连接的 C(R)-N < 残基一起代表完成杂环基所需的原子;和 R2 和 R3 可以相同或不同,各自可以是氢、任选取代的低级烷基、环烷基、芳基或被含一个或多个氮原子的杂环基取代的低级烷基;含一个或多个氮原子的杂环基;或 R2 和 R3 与各自所连接的 C(H)-N 残基一起独立地各自代表完成一个杂环基所需的原子;R.是 OH CH3;或苯基;R7 是氢或烷氧羰基或苄氧羰基;n 是 0、1、2 或 3;以及其与生理上可拆分的醇的酯或部分酯;式 I 化合物或其酯或部分酯分别与植物生理上可接受的酸或碱的盐,以及其所有光学异构体。
