Herein we report the asymmetric synthesis of 1,2-dipyridyl-1,2-diarylethanes via an unusual Cu(I)-catalyzed dimerization reaction. Subjection of a variety of enantioenriched substituted 2-pyridyl alcohols to a one-pot protocol generates the desired products in good yields and diastereoselectivities and with ee's up to >99%.
在此,我们报道了通过一种不寻常的铜(I)催化二聚反应实现1,2 - 二吡啶基 - 1,2 - 二芳基乙烷的不对称合成。将多种对映体富集的取代2 - 吡啶醇进行一锅法反应,可高产率、非对映选择性地生成所需产物,对映体过量值高达>99%。
