A general method for the synthesis of 2,3-disubstituted indoles is described. The key feature of this method is the amination of aromatic C−H bonds via FeCl2-catalyzed ring opening of 2H-azirines. The method tolerates a variety of functional groups such as Br, F, NO2, OMe, CF3, OTBS, alkenes, and OPiv. The method can also be extended to synthesize azaindoles.
The site‐selective allylative and allenylative dearomatization of indoles with alcohols was performed under carbocatalytic regime in the presence of grapheneoxide (GO, 10 wt % loading) as the promoter. Metal‐free conditions, absence of stoichiometric additive, environmentally friendly conditions (H2O/CH3CN, 55 °C, 6 h), broad substrate scope (33 examples, yield up to 92 %) and excellent site‐ and
在碳催化作用下,在氧化石墨烯(GO,10 wt%负载)作为促进剂的情况下,用醇对吲哚进行位点选择性烯丙基和烯丙基脱芳香化反应。无金属的条件,无化学计量的添加剂,环境友好的条件(H 2 O / CH 3 CN,55°C,6 h),广泛的底物范围(33个实例,产率高达92%)以及出色的定点和立体选择性目前的方法。此外,GO功能发挥的共价激活模型得到了光谱,实验和计算证据的证实。还记录了通过简单的酸性处理来回收和再生GO催化剂。
