Abstract An efficient, cost effective and commercially viable synthesis of dolutegravir sodium has been developed from commercially available methyl 4-methoxy-3-oxobutanote through 1-(2,2-dimethoxyethyl)-5-methoxy-6-(methoxycarbonyl)-4-oxo-1,4-dihydropyridine-3-carboxylic acid as the keyintermediate. The key features of the synthesis are lower number of synthetic steps and the use of eco-friendly
摘要 从市售甲基 4-methoxy-3-oxobutanote 通过 1-(2,2-dimethoxyethyl)-5-methoxy-6-(methoxycarbonyl)-4-oxo 开发了一种高效、成本有效且商业上可行的多替拉韦钠合成方法-1,4-二氢吡啶-3-羧酸作为关键中间体。该合成的主要特点是合成步骤数量较少以及使用环保且廉价的试剂。该过程已被证明可以满足 ICH 关于扩大规模的要求。
