useful linchpin in an efficient three-component coupling process. The reaction features a [1,4]-Brook rearrangement to generate the silylallyl anion, which adopts a predominant endo-orientation and can undergo addition to electrophiles in a regio- and stereoselective manner, giving various E-vinylsilane species in good yields.
通过3,3-双甲硅烷基醛与甲醛的曼尼希反应制备的双甲硅烷基烯醛在有效的三组分偶联过程中被证明是有用的关键。该反应有[1,4] -Brook重排以产生silylallyl阴离子,其采用主要内-orientation和可经历除了在一个区域选择性和立体选择性的方式电体,给各种ê -vinylsilane物种以良好的收率。
