The new coupling reaction of phenacylamines with silylstannane and lithium diisopropylamide (LDA) is reported. The treatment of a phenacylamine iodide 1 with (trimethylsilyl)tributylstannane (Me3SiSnBu3) and cesium fluoride (CsF) gave a dimerization product 2 having no iodine atom. Reaction of 1 with LDA afforded a dimerization product 3 with an iodine atom. The products 2 and 3 were separated to the meso and racemic isomers, respectively.
报道了苯甲酰胺与甲硅烷基锡烷和二异丙基氨基锂(LDA)的新偶联反应。用(三甲基甲硅烷基)三丁基锡烷(Me 3 SiSnBu 3 )和氟化铯(CsF)处理苯甲酰碘化胺1,得到不含碘原子的二聚产物2。 1与LDA反应得到带有碘原子的二聚产物3。产物2和3分别分离为内消旋异构体和外消旋异构体。
