[structure: see text] The synthesis of an advanced component leading to (-)-kendomycin is described. The synthetic scheme features the application of asymmetric conjugate addition methodology for the early generation of the C13-C14 (E)-trisubstituted olefin, providing an efficient assembly of the ansa chain. Condensation reactions probe two strategies for attachment of the aromatic system.
[结构:见正文] 描述了导致(-)-肯多霉素的一种高级组分的合成。该合成方案的特点是应用不对称共轭加成方法来早期生成C13-C14(E)-三取代烯烃,从而高效组装桥链。缩合反应探索了连接芳香体系的两种策略。
