A new facile entry to the synthesis of 1,3-bis(indol-3-yl)butane-1-ones is presented. The procedure effectively utilizes a InBr 3 /TMSCl mixture (10 mol%) as a promoter for the chemoselective Michael addition of variously functionalised indoles to α,β-unsaturated indolyl ketones. The excellent yields and the mildness of the experimental conditions guarantee a widespread applicability of the protocol
介绍了合成 1,3-双(indol-3-yl)butane-1-ones 的一种新的简便方法。该过程有效地利用 InBr 3 /TMSCl 混合物 (10 mol%) 作为促进剂,将各种官能化的吲哚化学选择性迈克尔加成到 α,β-不饱和吲哚酮上。优异的产率和温和的实验条件保证了该方案对构建功能化的酮基双(吲哚基)化合物的广泛适用性。
