Outside the limits: In the title reaction the nucleophile 1 represents a synthetic equivalent of nucleophilic allylic nitriles and addresses some of the current limitations associated with reactions of allylic nitrile anions. Unsaturated nitriles containing a trisubstituted double bond are obtained in high yield, with excellent site selectivity and good to excellent stereoselectivity (see scheme; LDA=lithium
超出范围:在标题反应中,亲核试剂1代表亲核烯丙基腈的合成等价物,并解决了当前与烯丙基腈阴离子反应相关的一些限制。以高产率获得含有三取代双键的不饱和腈,具有出色的位点选择性和良好的立体选择性(参见方案;LDA=二异丙基氨基锂)。
