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
