Abstract
The title compound 3 has been prepared via a highly selective, Cu(II)-mediated cross-coupling of 2-aminonaphthalene 1 and 2-naphthol 2 and resolved into enantiomers via crystallization of diastereoisomeric salts with (1S)-(+)-10-camphorsulfonic acid. The method has been optimized and the use of chromatography eliminated.
Keywords: Binaphthyls; Oxidative coupling; Resolution.
