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-cyano-3(R)-hydroxybutanoate as a chiral synthon for the stereospecific introduction of the 4-hydroxy-3,4,5,6-tetrahydro-2H-pyran-2-one moiety.
这项发明涉及一种新型工艺,用于制备含有4-羟基-3,4,5,6-四氢-2H-吡喃-2-酮基团的3-羟基-3-甲基戊二酰辅酶A(HMG-CoA)还原酶抑制剂,如紧凑素和美伐鲁,通过利用烷基4-氰基-3(R)-羟基丁酸酯作为手性合成子,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。
