Herein we report a microwave assisted Ru(III)/TBHP-mediated reaction of indoles with tetramethylurea (TMU) synthesizing symmetrical as well as unsymmetrical bis(indolyl)methanes, where TMU acts as a methylenating agent. This is the first report where TMU is used as a methylene source. Moreover, the synthesis of unsymmetrical bis(indolyl)methanes by using a carbon precursor is also reported herein for
本文中,我们报道了微波辅助Ru(III)/

吲哚与四甲基
脲(TMU)合成对称以及不对称的双(
吲哚基)
甲烷的反应,其中TMU作为甲基化剂。这是第一个使用TMU作为亚甲基来源的报告。此外,本文还首次报道了通过使用碳前体合成不对称的双(
