Abstract: Novel herbicidally active sulfonamide compounds having a 2-arylsubstituted oxiranylmethyl structure are racemates due to a chiral carbon in the oxirane moiety. To clarify the stereochemical structure-activity relationship, we synthesized each enantiomer of 4-chloro-N-[2-(6-chloropyridin-2-yl)-2-oxiran-2-ylmethyl]-3,N-dimethylbenzenesulfonamide and N-[2-(6-chloropyridin-2-yl)-2-oxiran-2-ylmethyl]-N-methyl-5,6,7,8-tetrahydronaphthalene-2-sulfonamide by chemical methods including Sharpless asymmetric chlorohydroxylation. The results of herbicidal tests indicated that the (S)-isomers were the active forms.
