A scalable, asymmetric route for the synthesis of the influenza virus replication inhibitor 2 is presented. The key steps include an enzymatic desymmetrization of cis-1,3-cyclohexanediester in 99% yield and 96% ee, SNAr displacement of a methanesulfinylpyrimidine, and a Curtius rearrangement to form a morpholinyl urea. This high-yielding route allowed us to rapidly synthesize hundreds of grams of 2
提供了用于合成流感病毒复制抑制剂2的可扩展的不对称路线。关键步骤包括:以99%的收率和96%ee进行顺式-1,3-环己烷二酯的酶促脱对称化,甲烷亚砜基嘧啶的S N Ar置换以及Curtius重排形成吗啉基脲。这种高产途径使我们能够以99%的纯度快速合成数百克2,以支持体内研究。
