Objective: To synthesis (3S,5S)-epimers of Atorvastatin Calcium. Methods: the (R)-ethyl-4-chloro-3-hydroxybutanoate was used a.s raw material and the (3S,5S)-epimers of Atorvastatin Calcium was obtained by cyanidation, condensation of carbonyl group, O-alkylation,condensation of cyanogroup, Paal-Knorr reaction with M-4, deprotection, hydrolysis of ester, salinization. The structures were confirmed by 1^H-NMR, ESI-MS, HPLC. Conclusion: The target compound was synthesized by this method, which provides an important reference for the research on impurities of atorvastatin.
