Abstract:Rosuvastatin calcium was synthesized using cyclopentyl(4R-cis)-6- [(acetyloxy)methyl]-2,2-dimethyl-1,3-dioxane-4-acetate and[[4-(4-fluorophenyl)-6-(1-methylethyl)-2-[N-methyl-(N-methylsulfonyl)amino]-5-pyrimidinyl]methyl]triphenylphosphonium bromid as the starting materials through a series of reactions including Witting reaction, hydrolysis, salination. The structure of Locaserin hydrochloride and some intermediates were confirmed by ESI-MS and 1H NMR, and the total yield of the product was 79.2%.
