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
