摘要我们描述了一种新的和直接的方法,正式合成的B型肝炎病毒抑制剂恩替卡韦,一个重要的B型肝炎药物,在10个步骤。该路线的关键特征是Morita-Baylis-Hillman反应、Sharpless不对称环氧化、α,β-环氧酮的还原性环氧开环和Riley二氧化硒氧化。
Abstract 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.
