A novel approach to the syntheses of aldosterone and naturally occurring analogues thereof is described. The strategy is characterized by a common and highly convergent route using the transannular Diels-Alder reaction of 14-membered TCC macrocyclic trienes as the key step. For this purpose, a novel macrocyclization procedure involving the intramolecular displacement of an α-chloroketone by a β-ketoester
描述了合成醛固酮及其天然存在的类似物的新方法。该策略的特点是使用14元TCC大环三烯的跨环Diels-Alder反应作为关键步骤的通用且高度收敛的路线。为此目的,涉及通过β-酮酸酯在分子内置换α-氯酮的新颖的大环化方法以高收率提供了三个关键的反式融合大环。
