SUBSTITUTED ESTERS OF 6-AMINO-7-PHENYL-3-(PHENYLIMINO)-4,7-DIHYDRO-3H-[1,2]DITHIOLO[3,4-B]PYRIDINE-5-CARBOXYLIC ACID AS ANTIDOTES 2,4- D IN SUNFLOWER Russian patent published in 2023 - IPC C07D495/02 C07D515/02 A01N43/26 A01N43/42 A01P15/00

Abstract RU 2799422 C1

FIELD: agriculture.

SUBSTANCE: invention relates to new synthetic, chemical biologically active substances used to protect sunflower plants from the phytotoxic effect of the herbicide 2,4-dichlorophenoxyacetic acid. Substituted esters of 6-amino-7-phenyl-3-(phenylimino)-4,7-dihydro-3H-[1,2]dithiolo[3,4-b]pyridine-5-carboxylic acid of formula (1-3) are proposed:

where (1) - R = _С2Н5, Ar = 2-thienyl; (2) - R\u003d CH₃, Ar\u003d 4-CH₃OC₆H₄; (3) - R = С₂Н₅, Ar = 4-CH₃OC₆H₄, which exhibit antidote activity against 2,4-dichlorophenoxyacetic acid in sunflower.

EFFECT: new substituted esters of 6-amino-7-phenyl-3-(phenylimino)-4,7-dihydro-3H-[1,2]dithiolo[3,4-b]pyridine-5-carboxylic acid formulas 1-3 expand the range of biologically active substances exhibiting antidote properties have high antidote activity.
