An efficient enantioselective synthetic route to atorvastatin was developed based on a direct catalytic asymmetric aldol reaction. The expensive chiral ligand used in the initial aldol reaction was readily recovered (91 %) and reused. Implementation of an oxy‐Michael reaction for the construction of the syn‐1,3‐diol unit eliminated several redundant steps, allowing for rapid access to the common intermediate
基于直接催化不对称醛醇缩合反应,开发了一种有效的对映阿托伐他汀的对映选择性合成途径。最初的醛醇缩合反应中使用的昂贵的手性配体易于回收(91%)并重复使用。实施辛-1,3-二醇单元的氧基-迈克尔反应的实施消除了几个多余的步骤,从而允许在六个步骤中快速进入通用中间体(参见方案)。
