High five! A novel, facile, and highly stereoselective synthesis of the title compounds has been developed with the control of five stereogenic centers through an organocatalytic asymmetric one‐pot tandem process involving a diastereoselective intramolecular nitrone [3+2] cycloaddition (see scheme).
举手击掌!通过涉及非对映选择性分子内硝酮[3 + 2]的非对映选择性单锅串联过程,开发了一种新颖,简便且高度立体选择性的标题化合物合成方法,该方法通过控制五个立体生成中心来控制(见方案)。
