Product Description
Metolachlor is an organiccompound thatis widely used as an herbicide. It is a derivative of aniline and is a member ofthe chloroacetanilide family of herbicides. It is highly effective toward grasses.Metolachlor is produced from 2-ethyl-6-methylaniline (MEA) viacondensation with methoxyacetone. The resulting imine is hydrogenated to give primarilythe S-stereoisomeric amine. This secondaryamine isacetylated with chloroacetylchloride. Because of the stericeffects ofthe 2,6-disubstituted aniline, rotation about the aryl-C to N bond is restricted. Thus, both the (R)- and the (S)-enantiomers existas atropisomers. Both atropisomers of (S)-metolachlor exhibit the samebiological activity.
