A general synthetic scheme for tamoxifen-typetetrasubstitutedolefins based on the novel Cu-catalyzed carbomagnesation acrossalkynyl(2-pyridyl)silane has been developed. A wide array of electronically and structurally diverse tetrasubstitutedolefins can be prepared in a regiocontrolled, stereocontrolled, and diversity-oriented manner. Noteworthy features are that (i) the three aryl groups, which

已经开发了基于新型 Cu 催化的炔基(2-吡啶基)硅烷碳镁化反应的他莫昔芬型四取代烯烃的一般合成方案。可以以区域控制、立体控制和面向多样性的方式制备各种电子和结构不同的四取代烯烃。值得注意的特征是 (i) 被认为对抗雌激素活性很重要(必不可少)的三个芳基可以随意变化,因为它们都源于容易获得的芳基碘化物,以及 (ii) 任何立体和原则上,区域异构体可以通过简单地改变芳基碘化物的应用顺序来制备。
