Divinylketone and the trimethylsily enol ethers of cyclohex-2-en-1-ones undergo Lewis acid assisted triple Michael reactions yielding tricyclo[5.3.1.03,8]undecan-4,11-diones; the application of this reaction enabled a formal synthesis of (±)-seychellene (5).
环己-2-烯-1-酮的二乙烯基酮和三甲基甲硅烷基烯醇醚进行路易斯酸辅助的三重迈克尔反应,生成三环[5.3.1.0 3,8 ]十一碳烷-4,11-二酮;该反应的应用使得能够正式合成(±)-seychellene(5)。
