A library of differently substituted 3,4,5-triaryl-2,6-dimethylpyridines and 2,3,5-triaryl-4,6-dimethylpyridines were synthesized and characterized using the Suzuki-Miyaura cross-couplingreaction with accordingly selected tribromodimethylpyridines and arylboronic acids. The optimized coupling conditions were found to be general for both isomeric tribromodimethylpyridines and a wide range of arylboronic
A convenient and general method for the preparation of sixteen 3,5-diarylsubstituted 2,4- and 2,6-dimethylpyridines of high forensic importance is described. The Suzuki cross-coupling reaction between a range of ring-substituted phenylboronic acids and 3,5-dibromo-2,4-dimethylpyridine and 3,5-dibromo-2,6-dimethylpyridine was used as a key step.
