α-hydroxycarboxylic acid anilides via copper-catalyzed chemoselective C–N coupling reactions of α-hydroxyamides and arylhalides is described. This highly selective N-arylation process demonstrates wide substrate scope, cost savings and easy operation. In addition, the chirality of l-3-phenyllactamide is preserved during the reaction. The synthesis of highly important α-hydroxycarboxylic acid anilides via copper-catalyzed
Novel mandelic acid derivatives containing piperazinyls as potential candidate fungicides against Monilinia fructicola: Design, synthesis and mechanism study
fungus , has caused significant losses to the agricultural industry. In order to explore and discover potentialfungicides against , thirty-one novel mandelic acid derivatives containing piperazine moieties were designed and synthesized based on the amide skeleton. Among them, target compound exhibited obvious antifungal activity with the EC value of 11.8 mg/L, and significant effects for the postharvest
