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.
建立了钯催化的两倍或四倍胺化反应,该反应可以区域特异性合成1,2-二取代(杂)芳基稠合的咪唑的多样性导向文库,并为发现具有可调荧光发射的荧光支架提供了出色的工具。这些荧光团已被用作活细胞成像的荧光探针。
