The present invention relates to quinoxalinone derivatives of formula (I), wherein R1, R2, R3, R4, R5 and R6 are as defined in claim 1, as insulin secretion stimulators. The invention also relates to the preparation and use of these quinoxalinone derivatives for the prophylaxis and/or treatment of diabetes and pathologies associated. Other preferred compounds are compounds of general formula (I), wherein R1, R2, R3, R4, R5 and R6 can be optionally substituted by one or more groups selected from Z.

yields. The ability to incorporate various protecting groups makes the imidoyl dichloride reagent amenable to a large number of syntheses. The reagent is applied to the total synthesis of the 2-aminobenzimidazole containing carcinogen, 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), from 2-chloro-3-nitropyridine in >60% yield in 6 steps.
提出了在室温下有效合成五元和六元唑的试剂的开发。合成了多种取代的2-氨基苯并咪唑,收率良好至优异。掺入各种保护基的能力使亚氨酰二氯化物试剂适合于大量合成。该试剂可用于由> 60的2-氯-3-硝基吡啶全合成含2-氨基苯并咪唑的致癌物2-氨基-1-甲基-6-苯基咪唑并[4,5- b ]吡啶(PhIP) 6个步骤中的%收率。
A mild inter- and intramolecular amination of aryl halides with a combination of CuI and CsOAc
combination of CuI and CsOAc was found to catalyze aryl amination under mild conditions. The reaction takes place at room temperature or at 90 °C with broad functional group compatibility. The intramolecular reaction was able to form five-, six-, and seven-membered rings with various protecting groups on the nitrogen atom. The scope of the intermolecular amination, as well as its applications to unsymmetrical
A selenium‐catalyzed carbonylative reaction for the synthesis of 2‐benzimidazolones from 2‐nitroanilines has been developed. In this strategy, to avoid the usage of toxic CO gas, TFBen (benzene‐1,3,5‐triyl triformate) was used as a solid and stable CO precursor, and a variety of desired 2‐benzimidazolones were produced in moderate to excellent yields.
