The invention relates to commercially viable process for the preparation of Rosuvastatin by an early introduction of the correct absolute stereochemistry at C-5 (S) of Rosuvastatin side chain followed by regioselective chain extension using novel side chain building blocks. It is yet another object of the invention is to provide novel intermediates that may be used for the preparation of Rosuvastatin. Formula (I).
本发明涉及一种商业上可行的过程,通过在Rosuvastatin侧链的C-5(S)处提前引入正确的绝对立体
化学,然后使用新的侧链构建块进行区域选择性链延伸,制备Rosuvastatin。本发明的另一个目的是提供可用于制备Rosuvastatin的新型
中间体。公式(I)。
