[图表]描述了合成天然产物schweinfurthin A、B和D的六羟基蒽部分的策略。在关键的阳离子环化步骤中的相对立体化学是通过苯基硒醚取代基对赤道取向的偏好来建立的。
[GRAPHICS]A strategy for synthesis of the hexahydroxanthene moiety of the natural products schweinfurthin A, B, and D is described. The relative stereochemistry in the key cationic cyclization step is established through the preference of the phenylselenide substituent for an equatorial orientation.
