A novel marine natural product, (+)-aureol (1), was efficiently synthesized starting from the cis-fused decalin derivative 4. The synthetic method features boron trifluoride etherate-promoted rearrangement/cyclization reaction of (+)-arenarol (2) to form (+)-aureol (1) with complete stereoselectivity in high yield. (+)-Arenarol (2) was prepared in an alternative and more efficient manner employing
从顺式融合十氢萘衍生物4开始有效地合成了新型海洋天然产物(+)-aureol(1)。该合成方法的特征在于,三氟化硼醚化物促进了(+)-芳烃(2)的重排/环化反应,从而以高收率完全立体选择性地形成了(+)-aureol(1)。(+)-Arenarol(2)是以替代方式和更有效的方式使用苏木素氧化方案制备的。
