A practical strategy for the synthesis of both (–)- and (+)-concentricolide from salicylic acid has been developed. The key feature of the approach is sequential aromatic lithiation and condensation with an aldehyde directed by a chiral oxazoline unit derived either from L- or D-phenylalaninol, which is employed as an auxiliary.
已经开发出一种从水杨酸合成 (-)- 和 (+)- 同心圆内酯的实用策略。该方法的关键特征是与醛的顺序芳族锂化和缩合,醛由 L- 或 D-苯丙醇衍生的手性恶唑啉单元引导,用作助剂。
