Isoquinolinone compounds are provided that are useful for the inhibition of ADP-platelet aggregation, particularly in the treatment of thrombosis and thrombosis related conditions or disorders.
calculations show that this cascade procedure involves the deoxygenative reduction of nitroarenes, the Maillard reaction, and hydrogenation to produce dihydroquinoxalinones and tetrahydroquinoxalines. This method aims to reduce the environmental impact while maintaining high yields and selectivity for both nitroarene reduction and the synthesis of dihydroquinoxalinones and tetrahydroquinoxalines.
开发了一种无金属一锅级联工艺,包括还原硝基芳烃、环化以及用 B 2 cat 2和水对亚胺进行连续氢化,以直接从容易获得的 2-硝基苯胺或邻二硝基苯与 α-酮酯构建二氢喹喔啉酮和四氢喹喔啉和α-二酮。该策略以良好至优异的产率和对许多官能团的耐受性提供了各种二氢喹喔啉酮和四氢喹喔啉。通过控制实验和密度泛函理论(DFT)计算进行的机理研究表明,该级联过程涉及硝基芳烃的脱氧还原、美拉德反应和氢化生成二氢喹喔啉酮和四氢喹喔啉。该方法旨在减少对环境的影响,同时保持硝基芳烃还原和二氢喹喔啉酮和四氢喹喔啉合成的高产率和选择性。
