The first asymmetric synthesis of (+)-iso-6-cassine is described. Lipase-catalyzed resolution, enantioselective Overman rearrangement, and diastereoselective intramolecular amidomercuration were used for the installation of the three stereocenters in (+)-iso-6-cassine, and cross-metathesis was employed for the attachment of the side-chain.
描述了 (+)-iso-6-cassine 的第一个不对称合成。脂肪酶催化拆分、对映选择性 Overman 重排和非对映选择性分子内酰胺化反应用于在 (+)-iso-6-cassine 中安装三个立体中心,并采用交叉复分解作用连接侧链。
