The stereocontrolled synthesis of atorvastatin calcium from commercially available d-aspartic acid using intramolecular oxidative oxygen-nucleophilic bromocyclization of homoallylic tert-butyl carbonate is described. This strategy allows formation of the chiral syn-1,3-diol moiety in the desired stereochemistry and provides a functionalized bromomethyl group for construction of the atorvastatin side
描述了使用分子内氧化氧-亲核溴环化同烯丙基叔丁基碳酸酯从市售 d-天冬氨酸中立体控制合成阿托伐他汀钙。该策略允许在所需立体化学中形成手性合成-1,3-二醇部分,并提供功能化的溴甲基,用于构建具有高区域和非对映控制的阿托伐他汀侧链。该路线作为大规模合成他汀类药物分子及其类似物的有效环境敏感方法很有吸引力。
