Convenient synthesis of selected meta- and ortho- substituted pentaarylpyridines via the Suzuki-Miyaura cross-coupling reaction

Uproszczony widok
dc.abstract.enThe first synthesis of sterically demanding, stable at room temperature atropisomeric derivatives of penta-(ortho-substituted phenyl)pyridines is described. The Suzuki-Miyaura cross-coupling reaction of pentabromopyridine and selected meta- and ortho-tolylboronic acids afforded a series of pentaarylpyridine derivatives. The structures of two room temperature stable atropisomeric derivatives of penta-(o-tolyl)pyridines were confirmed by single-crystal X-ray analysis. Racemic atropisomers were examined by 1H NMR spectroscopy with a chiral solvating agent in order to visualize the presence of individual enantiomers.
