A concise and efficient asymmetric synthesis of tert-butyl [(4R,6R)-6-(2-aminoethyl)-2,2-dimethyl-1,3-dioxan-4-yl]acetate is presented. This key chiral-chain precursor of atorvastatin was synthesized from a commercially available inexpensive starting material, and was converted into atorvastatin calcium. The synthesis has the potential for scale up, and could be used to produce atorvastatin calcium
介绍了[(4 R ,6 R )-6-(2-氨基乙基)-2,2-二甲基-1,3-二氧杂环己烷-4-基] 乙酸叔丁酯的简洁高效的不对称合成。阿托伐他汀的这种关键手性链前体是从市售的廉价起始材料合成的,并被转化为阿托伐他汀钙。该合成具有扩大规模的潜力,可用于工业规模生产阿托伐他汀钙。
