We describe a new and straightforward approach to the formal synthesis of the hepatitis B virus inhibitor entecavir, an important hepatitis B drug, in ten steps overall. Key features of the route are a Morita–Baylis–Hillman reaction, a Sharpless asymmetric epoxidation, a reductive epoxide opening of an α,β-epoxy ketone, and a Riley selenium dioxide oxidation.
我们描述了一种新的、直接的方法来正式合成乙型肝炎病毒抑制剂恩替卡韦,一种重要的乙型肝炎药物,总共分为十个步骤。该路线的主要特征是 Morita-Baylis-Hillman 反应、Sharpless 不对称环氧化、α,β-环氧酮的还原环氧化物开环和 Riley 二氧化硒氧化。
