Abstract

More than seventy years ago, Gilman [1] and Wittig [2] independently observed that the lithiation of an aromatic ring could be achieved ortho to a substituent, and hence opened up new horizons for obtaining differently functionalized organolithium derivatives through what is today known as the directed ortho metalation (DoM) reaction. Since then, and particularly thanks to seminal contributions from the groups of Hauser, Meyers, Gschwend, Beak, ...
