Abstract

A palladium-catalyzed two or fourfold amination was established that allows regiospecific synthesis of a diversity-oriented library of 1,2-disubstituted (hetero)aryl fused imidazoles, and provides an exceptional tool for the discovery of fluorescent scaffolds with tunable fluorescence emission. These fluorophores have been applied as fluorescent probes for live cell imaging.
