Abstract
A simple and facile synthesis of novel 4-aryl-2-chloro-, 2,4-diaryl- and 2,4,7-triarylpyrrolo[2,3-d]pyrimidines with various aryl and heteroaryl assemblies in the heterocyclic framework by a combination of Suzuki cross-coupling and N-arylation reactions of 2,4-dichloropyrrolo[2,3-d]pyrimidine with arylboronic acids and haloarenes are described. A majority of the synthesized compounds were found to emit in a near UV-blue spectral range with fluorescence quantum yields up to 67%. The impact of aryl groups attached to the pyrrole ring of pyrrolopyrimidine derivatives on optical properties is discussed.
