The trimethylsilyl enol ethers of 1-acetylcyclohexenes undergo a Lewis-acid-assisted one-pot annelation reaction with α,β-unsaturated carbonyl compounds to produce 5-substituted 2-decalones; the application of this reaction has enabled a synthesis of (±)-ε-cadinene (12).
1-乙酰基环己烯的三甲基甲硅烷基烯醇醚与α,β-不饱和羰基化合物进行路易斯酸辅助的一锅法成环反应,生成5-取代的2-癸酮。该反应的应用已使(±)-α-卡丁烯(12)的合成成为可能。
