Novel Stereocontrolled Approach tosyn- andanti-Oxepene–Cyclogeranyltrans-Fused Polycyclic Systems: Asymmetric Total Synthesis of (−)-Aplysistatin, (+)-Palisadin A, (+)-Palisadin B, (+)-12-Hydroxy-Palisadin B, and the AB Ring System of Adociasulfate-2 and Toxicol A

the construction of trans-syn 6,7-ring systems. This approach leads to the synthesis of the AB fragment of Adociasulfate-2 and Toxicol A, for the first time. The flexibility and efficiency of the presented strategy is demonstrated by the total asymmetric synthesis of (-)-Aplysistatin, (+)-Palisadin A, (+)-12-hydroxy-Palisadin B, and (+)-Palisadin B, employing two similar key intermediates.
