coupling reactions were developed. First, the copper-catalyzed coupling of uracil with aryl iodides, employing picolinamide 16 as the ligand, was discovered. Later, the palladium-catalyzed sulfonamidation of aryl nonaflate 33 was developed, promoted by electron-rich palladium complexes, including the novel phosphine ligand, VincePhos (50). This made possible a convergent, highly efficient synthesis
Dasabuvir ( 1 ) 是一种 HCV 聚合酶抑制剂,已被开发为三组分直接作用抗病毒联合疗法的一部分。在合成路线的开发过程中,开发了两种新的偶联反应。首先,发现了使用吡啶酰胺16作为配体的尿嘧啶与芳基碘化物的铜催化偶联。后来,在富电子钯配合物(包括新型膦配体 VincePhos ( 50 ))的推动下,开发了钯催化的芳基非磺酸盐33 的磺酰胺化反应。这使得达沙布韦的收敛、高效合成成为可能,显着降低了该过程的诱变杂质负担。
