A series of novel substituted 3-(pyridin-2-yl)benzenesulfonamide derivatives were designed and synthesized using 2-phenylpridines as the lead compound by intermediate derivatization methods in an attempt to obtain novel compound candidates for weed control. The herbicidalactivity assay in glasshouse tests showed several compounds (II6, II7, II8, II9, II10, II11, III2, III3, III4, and III5) could efficiently

Ligand exchange reaction of sulfoxides in organic synthesis: A new method for generation of magnesium enolates of α-chloro carboxylic acids and their derivatives
Treatment of α-chloro α-sulfinyl carboxylic acid derivatives with EtMgBr in THF at low temperature gave magnesium enolates of the α-chloro carboxylic acid derivatives. The enolates reacted with ketones and aldehydes to afford aldol compounds (or α,β-epoxy acids) in good yields.
