A full carbon skeleton of the natural product lomaiviticin has been synthesized. The approach features anionic annulation reactions to deliver A and B rings of the natural product, and stereoselective oxidative enolate coupling to form the central C2C2′ σ bond. In the course of the investigation, a remarkable substituent effect at C11 position was observed.
已合成天然产物洛麦维霉素的全碳骨架。该方法具有阴离子环化反应以传递天然产物的 A 和 B 环,以及立体选择性氧化烯醇耦合以形成中心 C2 C2' σ 键。在研究过程中,观察到在 C11 位有显着的取代作用。
