The stereoselective total synthesis of (−)-brevisamide, a novel marine cyclic ether alkaloid isolated from dinoflagellate karenia brevis is described. The key steps involved in this synthesis are the Sharpless asymmetric epoxidation and regioselective ring opening of chiral epoxide by Gilman's reagent. The tetrahydropyran core has been constructed by an intramolecular SN2 cyclisation.
描述了立体异构全合成的(-)-灯盏花酰胺,这是一种从短鞭毛小茴香中分离出的新型海洋环醚生物碱。合成过程中的关键步骤是吉尔曼试剂使Sharpless不对称环氧化和手性环氧化物的区域选择性开环。四氢吡喃核心已经通过分子内S N 2环化而构建。
