Abstract

The present disclosure relates to fungicidal active compounds, more specifically to benzosultams and analogues thereof, processes and, intermediates for their preparation and use thereof as fungicidal active compound, particularly in the form of fungicide compositions. The present disclosure also relates to methods for the control of phytopathogenic fungi of plants using these compounds or compositions comprising thereof.

First claim

The invention claimed is:

1. A compound selected from the group consisting of:
compounds of formula (IIa) and/or salts thereof:

wherein:
W is CH or N;
Y 7 is a hydrogen atom or a fluorine atom; and
U 8 is a fluorine atom, a bromine atom, a chlorine atom, an iodine atom, a hydroxyl group, an amino group, a mesyl group, a tosyl group or a triflyl group, wherein the compound of formula (IIa) does not represent:
3-bromo-8-fluoro-2-methylquinoline [1259519-95-3],
8-fluoro-2-methylquinolin-3-ol [1314012-55-9],
8-fluoro-2-methylquinolin-3-amine [1259519-93-1],
7,8-difluoro-2-methylquinolin-3-ol [1314012-50-4],
5-fluoro-3-methylquinoxalin-2(1H)-one [1426822-07-2],
2-chloro-5-fluoro-3-methylquinoxaline [1426822-08-3], and/or
2-chloro-5,6-difluoro-3-methylquinoxaline [1415018-73-3], and
compounds of formula (IIb) and/or salts thereof:

wherein:
Y 7 is a hydrogen atom or a fluorine atom; and
U 9 is a fluorine atom, a bromine atom, a chlorine atom, an iodine atom, a hydroxyl group, an amino group, a mesyl group, a tosyl group or a triflyl group, wherein the compound of formula (IIb) does not represent:
5-fluoroquinoxalin-2(1H)-one [55687-16-6],
5-fluoroquinoxalin-2-amine [1895170-02-1],
2-chloro-5-fluoroquinoxaline [55687-09-7],
5,6-difluoroquinoxalin-2(1H)-one [917343-50-1], and/or
2-chloro-5,6-difluoroquinoxaline [1384067-26-8].
