hepatitis C viral polymerase (HCVP) protein was executed via a racemic synthetic route coupled with chiral HPLC separation. Due to the achiral route and instability of key intermediates, the initial route was determined to be unsuitable for large-scale manufacture. An alternate route was developed utilizing a convergent Heck coupling, resolution of a carboxylic acid via diastereomeric salt formation, and
2-(4- 2-[(2 R)-2-环戊基-5-(5,7-二甲基-[1,2,4]三唑并[1,5-a]嘧啶-2-基甲基)的合成以多千克规模描述了)-4-羟基-6-氧代-3,6-二氢-2H-吡喃-2-基]-乙基} -2-氟-苯基)-2-甲基-丙腈(1)。该抑制丙型肝炎病毒聚合酶(HCVP)蛋白的临床候选物的初步合成是通过外消旋合成途径与手性HPLC分离相结合进行的。由于关键中间体的非手性路线和不稳定性,确定了初始路线不适合大规模生产。利用会聚的Heck偶联,通过非对映异构体盐的形成来拆分羧酸以及对不期望的对映异构体进行有效的化学循环,开发了另一种途径。
