A new enantioselective synthesis of the anti-influenza agent (−)-oseltamivir free base (7.1% overall yield; 98% ee) and (−)-methyl 3-epi-shikimate (16% overall yield; 98% ee) has been described from readily available raw materials. Sharpless asymmetric epoxidation and diastereoselective Barbier allylation of an aldehyde are the key reactions employed in the incorporation of chirality, while the cyclohexene
抗流感药物(-)-oseltamivir游离碱(7.1%的总产率; 98%ee)和3-- Epi- shikimate(-)-甲基-甲基(16%的总产率; 98%ee)的新对映体选择性合成从容易获得的原材料中进行描述。醛的无尖锐不对称环氧化和非对映选择性Barbier烯丙基化是手性结合过程中的关键反应,而环己烯羧酸酯核则是通过闭环易位反应构建的。
