Synthesis and intermediates
The invention relates to novel synthesis methods for the preparation of the intermediates, which are suitable for the preparation of statin derivatives, especially to novel synthesis methods of the intermediate of formula VI
wherein Ra' and Rc' are each independently of the other hydrogen or a hydroxy-protecting group or together are a bridging hydroxy-protecting group, and Rb is a carboxy-protecting group, which methods are carried out by conversion of the intermediate of formula XVI
wherein Ra' and Rc' are each independently of the other hydrogen or a hydroxy-protecting group, R* and R** are each independently of the other hydrogen or an amide-protecting group, and Rb is a carboxy-protecting group; which methods proceed to further new intermediates and methods for their preparation.
合成和中间体
本发明涉及制备适用于制备他汀衍生物的中间体的新型合成方法,尤其涉及式 VI 中间体的新型合成方法
其中,Ra'和 Rc'各自独立地为氢或羟基保护基团,或共同为桥接羟基保护基团,Rb 为羧基保护基团,这些方法通过式 XVI 中间体的转化来实现
其中,Ra'和 Rc'各自独立地为氢或羟基保护基团,R*和 R** 各自独立地为氢或酰胺基保护基团,Rb 为羧基保护基团;通过这些方法可进一步制备新的中间体及其制备方法。
