This invention relates to a novel process for the preparation of 3-hydroxy-3-methylglutarylcoenzyme A (HMG-CoA) reductase inhibitors which contain a 4-hydroxy-3,4,5,6-tetrahydro-2H-pyran-2-one moiety, such as compactin and mevinolin, by utilizing an alkyl 4-halo-3(S)-hydroxybutanoate as a chiral synthon for the stereospecific introduction of the 4-hydroxy-3,4,5,6-tetrahydro-2H-pyran-2-one moiety.
该发明涉及一种新型制备3-羟基-3-甲基戊二酰辅酶A(HMG-CoA)还原酶抑制剂的过程,该抑制剂含有一个4-羟基-3,4,5,6-四氢-2H-吡喃-2-酮基团,如紧凑素和美维诺林,通过利用烷基4-卤代-3(S)-羟基丁酸酯作为手性合成物,用于立体特异性引入4-羟基-3,4,5,6-四氢-2H-吡喃-2-酮基团。
