In order to study the insecticidal activity of o-carboxamidobenzamide compounds, to investigate the structure-activity relationships of these compounds, 2-amino-3-hydroxypropionic acid and substituted 2-nitrobenzoic acid were used as starting materials to synthesize 29 diamides target compounds containing 2-substituted phenyloxazole groups, the yields were in the range of 30% and 50%. The insecticidal activities of these compounds were investigated. To some extend, the title compounds showed insecticidal activity against oriental armyworm (Mythimna separata Walker) in vitro. 2-(2-bromophenyl)-N-(4-chloro-2-(methoxy carbamoyl)-6-methyl phenyl) oxazole-4-carbox-amide (compound 11p) showed the highest insecticidal activity among these compounds. The structure-activity relationship of these compounds was summarized and the compounds with high activity were obtained.

Key words: insecticide, o-carboxamidobenzamide compounds, benzoxazole compounds
