The first catalytic oxidative aniline-aniline cross-coupling reaction using oxygen as the terminal oxidant is reported. Anilines possessing a pyrrolidino group can be preferentially oxidized under mild aerobic conditions and reacted with other anilines to afford a variety of nonsymmetrical 2-aminobiphenyls with high selectivities. A heterogeneous palladium catalyst is used for the dehydrogenative cross-coupling

We have exploited a bis(1,10-phenanthroline)copper(I) visible light photocatalyst (VLP), [Cu(dap)2]+, to effect the direct α-C–H functionalization of amines. To our knowledge, this represents the first example of the oxidation of amines that are ultimately incorporated into synthetic targets by a copper(I) VLP. We have utilized this approach to rapidly prepare unprecedented octahydroisoquinolino[2
我们开发了一种双(1,10-菲咯啉)铜(I)可见光催化剂(VLP)[Cu(dap)2 ] +来实现胺的直接α-CH官能化。据我们所知,这是胺氧化的第一个例子,该胺最终被铜(I)VLP掺入合成靶中。我们已经利用这种方法快速制备了前所未有的八氢异喹啉[2,1- a ]吡咯并[3,4- c]喹啉框架并利用这一过程合成了天然产物麦角丙氨酸B的新型糖苷配基类似物。最重要的是,我们的研究表明,三氟乙酸(TFA)的存在对于介导推定的光激发铜(I )参与催化循环的物种。
