Based on a bioinspired asymmetric Diels–Alder cycloaddition using a chiral Evans oxazolidinone, the first total synthesis of both enantiomers of two myrcene-derived cyclohexenyl chalcones, fislatifolione and fislatifolic acid, has been carried out. This strategy was also applied to the total synthesis of nicolaiodesin C. These natural products, as well as their synthetic intermediates, were evaluated
基于使用手性 Evans 恶唑烷酮的仿生不对称 Diels-Alder 环加成反应,首次全合成了两种月桂烯衍生的环己烯基查耳酮、fislatifolione 和 fislatifolic 酸的两种对映异构体。该策略也应用于nicolaiodesin C的全合成。这些天然产物及其合成中间体通过体外亲和性分析进行评估。
