A novel and efficient synthesis of isatoicanhydride derivatives was developed via palladium-catalyzed multistep tandem carbonylation/N-dealkylation/carbonylation reaction with alkyl as the leaving group and tertiary anilines as nitrogen nucleophiles. This approach features good functional group compatibility and readily available starting materials. Furthermore, it provided a convenient approach for

carbonylation of N-alkyl anilines for the synthesis of isatoic anhydrides has been developed. The key Pd-catalyst intermediate has been isolated and characterized. This novel Pd-catalyzed carbonylation reaction tolerates a wide range of functional groups and is a reliable method for the rapid elaboration of readily available N-alkyl anilines into a variety of substituted isatoic anhydrides under mild conditions

(EN) A benzodiazepinedione derivative which acts as a nonpeptidyl platelet aggregation inhibitor is provided. This inhibitor potently inhibits fibrinogen binding to the GPIIbIIIa receptor and is provided in therapeutic compositions for the treatment of diseases for which blocking platelet aggregation is indicated. These nonpeptidyl inhibitors are provided in combination with thrombolytics and anticoagulants.(FR) Un dérivé de benzodiazépinedione intervient en tant qu'inhibiteur non peptidyle d'aggrégation des plaquettes. Il inhibe fortement la liaison des fibrinogènes au récepteur GPIIbIIIa et figure dans des compositions thérapeutiques relatives au traitement de maladies pour lesquelles il convient de bloquer l'aggrégation des plaquettes. Ces inhibiteurs non peptidyles sont combinés avec des thrombolytiques et des anticoagulants.
