and environmental impact issues of the initial synthesis. Highlights of the new synthesis include a highly selective methylation, 3−4-fold higher productivity, and a 65% reduction of combined organic and aqueous waste produced. The efficient second-generation manufacturing route provides raltegravir potassium 1 in 35% overall yield.
通过氨基mid肟DMAD加合物6的热重排,开发了合成raltegravir钾1的生产路线,以构建关键的,高度官能化的羟基嘧啶酮核心7。利用该路线1,以九个线性化学步骤制备,总产率为22%。随后开发了第二代合成方法,解决了最初合成方法中的关键化学,生产率和环境影响问题。新合成的亮点包括高度选择性的甲基化,高3-4倍的生产率以及所产生的有机废物和含水废物减少了65%。有效的第二代生产路线提供了拉格韦韦钾1 总产量的35%。
