[structure] A formal total synthesis of the natural product dysidiolide is described. Starting from a Diels-Alder reaction between an enoate and a Rawal diene, the cyclohexenone 4 was synthesized. A subsequent stereospecific methyl cuprate addition established the desired trans configuration in the cyclohexane 3. Wacker oxidation of the pentenyl side chain to the diketone 17 followed by an intramolecular
[结构]描述了天然产物dysidiolide的正式全合成。从烯醇酸酯和拉瓦尔二烯之间的狄尔斯-阿尔德反应开始,合成了环己烯酮4。随后的立体有择铜酸甲酯的添加在环己烷3中建立了所需的反式构型。戊烯基侧链的瓦克氧化成二酮17,随后分子内的羟醛缩合,生成了双环烯酮2,这是最近报道的嘧啶二醇合成中的关键中间体。 。
