diastereomeric 1,4-adducts. The reaction is kinetically controlled in toluene, whereas thermodynamically in refluxing THF. 4-Methyl-3-penten-2-one and carvone analogously give the respective 1,4-adducts and a conjugated dienone addords the 1,6-adduct in good yield.
三乙基铝介导的氰基三甲基硅烷与6-甲基双环[4.4.0] dec-1-en-3-one的反应提供非对映异构体1,4-加合物的混合物。该反应在甲苯中是动力学控制的,而在回流的THF中是热力学控制的。4-甲基-3-戊烯-2-酮和香芹酮类似地给出各自的1,4-加合物,而共轭二烯酮加成1,6-加合物的收率很好。
