摘要： The application describes a new process for preparing Simvastatin from Lovastatin amine salts in three steps. Lovastatin was hydrolysed to acid form and then isolated in the form of amine salt like cyclopropyl or t-octyl amine etc. The salts isolated were methylated directly without any protection and deprotection of hydroxy groups. The Simvastatin ammonium salt was produced directly, converted to Simvastatin by conventional methods & then purified to Simvastatin.
摘要翻译：该申请描述了从洛伐他汀胺盐制备辛伐他汀的三个步骤的新方法。将洛伐他汀水解成酸形式，然后以胺盐形式分离，如环丙基或叔辛基胺等。分离的盐直接甲基化，无任何保护和羟基脱保护。辛伐他汀铵盐直接生产，通过常规方法转化为辛伐他汀，然后纯化至辛伐他汀。

摘要： The invention is a novel process for purification of macrolides such as Tacrolimus using a new polymer resin and copper salts containing cupric ions. The novel polymer resin contains polyvinyl pyrrolidone, metha acrylate, divinyl benzene based compounds. In the said process manufacturing of new polymer resin and use of cupric salt is very much cost effective. The same metal salts can also be used along with other neutral non-ionic adsorption resins of polyethylene i e HP2O, HP2OSS, Sepabeads SP207 and the like. The concentration of copper ions may be generally 0.20 to 1.5 mol/L, preferably 0.30 to 0.40 mol/L. As an aqueous medium for the copper ion containing aqueous solvent, an aqueous acetone, an aqueous alcohol, an aqueous acetonitrile or the like. The invention covers Tacrolimus having a purity of more than 99.7%.
摘要翻译：本发明是使用新的聚合物树脂和含有铜离子的铜盐来纯化大环内酯如塔克罗莫司的新方法。新型聚合物树脂含有聚乙烯吡咯烷酮，甲基丙烯酸酯，二乙烯基苯基化合物。在所述方法中制造新型聚合物树脂和使用铜盐是非常成本有效的。同样的金属盐也可以与聚乙烯的其它中性非离子吸附树脂一起使用，例如HP2O，HP2OSS，Sepabeads SP207等。铜离子的浓度通常为0.20〜1.5mol / L，优选为0.30〜0.40mol / L。作为含有铜离子的含水溶剂的水性介质，含水丙酮，含水醇，乙腈水溶液等。本发明涵盖具有超过99.7％纯度的他克莫司。
