The invention relates to commercially viable process for the synthesis of key intermediates for the preparation of statins, in particular Rosuvastatin and Pitavastatin or respective pharmaceutically acceptable salts thereof. A new simple and short synthetic route for key intermediates is presented which benefits from the use of cheap and readily available starting materials, by which the conventionally most frequently used DIBAL-H as reducing agent can be avoided.
本发明涉及一种商业可行的工艺,用于合成制备他汀类药物的关键中间体,尤其是罗舒瓦司汀和
匹伐他汀或其相应的药用盐。本发明提供了一种新的简单短路线用于合成关键中间体,该路线受益于使用廉价且易得的起始材料,从而可以避免传统上最常用的D
IBAL-H还原剂。
