Fluorinated nucleoside 1 is a key starting material in the synthesis of rovafovir etalafenamide (2), a novel nucleotide reverse transcriptase inhibitor under development at Gilead Sciences for the treatment of HIV. While an initial manufacturing route enabled the production of 1 to support clinical development, alternative approaches were explored to further enhance manufacturing effectiveness, improve
氟化核苷1是合成rovafovir etalafenamide(2)的关键起始原料,rovafovir etalafenamide(2)是吉利德科学公司正在开发的用于治疗HIV的新型核苷酸逆转录酶抑制剂。虽然最初的生产路线使1的生产能够支持临床发展,但仍在探索替代方法以进一步提高生产效率,缩短加工时间,降低成本并将对环境的影响降至最低。为此,开发了一条新的途径以合成一种关键的合成中间体,并使用一种新的保护基策略将其转化为1条。新的化学方法导致了制造工艺的改进,同时降低了总体工艺质量强度(PMI)。
