was demonstrated on 100 g scale and featured the key application of phenylboronic acid as an effective transient means to protect the 2′,3′-hydroxyls of 2′-C-methylcytidine. This synthetic methodology resulted in a reduction in the number of isolations from five to two and an increase in the overall yield by 50% relative to the original unscalable discovery route. The synthesis and characterization of
丙型肝炎病毒核苷酸前药抑制剂2'- C-甲基胞嘧啶5'-[2-[((3-羟基-2,2-二甲基-1-氧丙基)硫基]乙基-N-苄基氨基磷酸酯]的合成方法描述了NS5B聚合酶。所开发的路线在100 g规模上得到了证明,其特征在于苯硼酸作为保护2'- C-甲基胞嘧啶2',3'-羟基的有效瞬态手段的关键应用。相对于原始的不可扩展的发现路线,这种合成方法可以将分离次数从五个减少到两个,并使总产量增加50%。还提供了2' - C-甲基胞嘧啶-2',3'- O-苯基硼酸酯的合成和表征。
