The present invention relates to compounds of Formula (I), or an agronomically acceptable salt of said compounds wherein A, A, R, R, Rand Rand Rare as defined herein. The invention further relates to herbicidal compositions which comprise a compound of Formula (I), and to their use for controlling weeds, in particular in crops of useful plants. 

Herbicidal compounds

The present invention relates to compounds of formula (I), or an agronomically acceptable salt of said compounds wherein A, A, R, R, R, R, Rand Rare as defined herein. The invention further relates to herbicidal compositions which comprise a compound of Formula (I), and to their use for controlling weeds, in particular in crops of useful plants. 

Herbicidal quinolines

The present invention relates to compounds of Formula (I), or an agronomically acceptable salt of said compounds wherein A1, A2, R, R, Rand Rare as defined herein. The invention further relates to herbicidal compositions which comprise a compound of Formula (I), to their use for controlling weeds, in particular in crops of useful plants, and to intermediates used to synthesize said compounds. 

The present invention provides stereoselective processes for the preparation of compounds of formula (I) wherein P is phenyl, naphthyl, a 6-membered heteroaryl group containing one or two nitrogen atoms as ring members, or a 10-membered bicyclic heteroaryl group containing one or two nitrogen atoms as ring members, and wherein the phenyl, naphthyl and heteroaryl groups are optionally substituted; Ris chlorodifluoromethyl or trifluoromethyl; Ris optionally substituted aryl or optionally substituted heteroaryl; n is 0 or 1; including the process comprising (a-i) reacting a compound of formula II wherein P, Rand Rare as defined for the compound of formula I; with nitromethane in the presence a chiral catalyst to give a compound of formula III Wherein P, Rand Rare as defined for the compound of formula I; and (a-ii) reductively cyclizing the compound of formula III to give the compound of formula I. The invention also provides intermediates useful for processes for the synthesis of compounds of formula (I). 

Process for the preparation of dihydropyrrole derivatives
