Abstract
N,N-Ligands with combined binaphthyl/bipyridyl structure were synthesized b y palladium-catalyzed coupling of 1-naphthylboronic acids with 1-halogenois oquinoline derivates and with 4-bromo-2-(2-pyridyl)naphtho[2,3-d]-1,3-oxazo le. Racemic 1-(2-methoxy-1-naphthyl)-3-(2-pyridyl)isoquinoline was resolved via diastereomeric salt formation with (-)-3-bromocamphor-8-sulfonic acid and the absolute configuration was determined by X-ray analysis.
