Nucleophilic reactions of various enol silyl ethers with carbocation species generated from propargyl silyl ethers by the action of a Lewis acid have been developed. The present method is highly useful for the introduction of allenic or enyne functionalities into the alpha-position of substituted ketones. [reaction--see text]
已经开发了各种烯醇甲硅烷基醚与在路易斯酸作用下由炔丙基甲硅烷基醚产生的碳阳离子种类的亲核反应。本方法对于将烯丙基或烯炔官能团引入取代的酮的α-位置非常有用。[反应-见文字]
