Discovery of a Full-Color-Tunable Fluorescent Core Framework through Direct CH (Hetero)arylation of N-Heterocycles

All the colors of the rainbow! A full coverage of emission wavelengths in the visible region (405–616 nm) with large Stokes shifts in C3‐Indo‐Fluor may be straightforwardly and succinctly achieved by the palladium‐catalyzed direct CH arylation of indolizines at the C3 position of the pyrrole ring (...

Description
Summary:All the colors of the rainbow! A full coverage of emission wavelengths in the visible region (405–616 nm) with large Stokes shifts in C3‐Indo‐Fluor may be straightforwardly and succinctly achieved by the palladium‐catalyzed direct CH arylation of indolizines at the C3 position of the pyrrole ring (see figure). The fluorophores have successfully marked A375 cells.
