TOP class: The first efficient catalytic asymmetric coupling reaction of indoles with isatin‐derived nitroalkenes was accomplished by using a complex consisting of a chiral imidazoline aminophenol ligand (1; see scheme) and Cu(OTf)2. Biological activity of the newly formed chiral 3,3′‐bisindoles was also confirmed in a Wnt signaling inhibitory assay.
上一类:通过使用由手性咪唑啉氨基酚配体(1 ;参见方案)和Cu(OTf)2组成的配合物,实现了吲哚与靛红衍生的硝基烯烃的首次有效催化不对称偶联反应。Wnt信号抑制试验也证实了新形成的手性3,3'-双吲哚的生物活性。
