摘要: It is possible to produce oseltamivir safely and stably in large quantities by using as a starting material tartaric acid, mannitol or arabinose, via dihydroxyhexenoic acid ester of the formula (4c): (wherein R1, R2 and R6 are same or different and are each alkyl, aryl, substituted aryl, aralkyl, substituted aralkyl or aromatic heterocyclic group, and R1 and R2 are not methyl simultaneously).
