[2-(AZOL-1-YL)ALKYLBENZIMIDAZOL-1-YL]ALKANOIC ACIDS AND ESTERS THEREOF, METHOD OF PRODUCING SAID COMPOUNDS (VERSIONS) AND GROWTH-REGULATING COMPOSITION BASED ON SAID COMPOUNDS Russian patent published in 2010 - IPC C07D235/06 C07D235/20 C07D403/06 A01N43/52 A01P21/00 

FIELD: chemistry.

SUBSTANCE: invention relates to [2-(azol-1-yl)alkylbenzimidazol-1-yl]alkanoic acids and their esters of general formula I, where Z and Y represent a nitrogen atom or a CH-group, or are simultaneously a C-CH=CH-CH=CH-C chain, together consisting of an annelated ring, n and m are equal or different and assume integer values from 1 to 3, R is a hydrogen atom or an alkyl group with 1 to 4 carbon atoms, except [2-(1H-benzimidazol-1-ylmethyl)-1H-benzimidazol-1-yl]acetic acid. The said compounds with general formula I are obtained through alkylation of 2-(azol-1-ylalkyl)benzimidazoles II with esters of ω-halogenalkanoic acids alkylacrylates and γ-butyrolacton in polar aprotonic and protonic solvents in the presence of carbonates of alkali metals, as well as when using interphase transfer catalysts. The invention also relates to a growth-regulating composition based on compounds of general formula I.

EFFECT: use of the derivative in the growth-regulating composition allows for achieving a growth retardant effect.
