The novel 1,l'-binaphthyls with OH and/or NHR (R = H or Ph) groups in the 2,2'-positions and with additional methoxycarbonylgroup(s) in the 3- or 3,3'-poaitions (13-18) have been synthesized from their respective precursors 1-5 by the CuCld t-BuNH2-mediated oxidative crow-coupling. In most cases, the chemoselectivity was good, and the cross-coupled products 11-18 were obtained in fair to excellent yields. Binaphthyls 6-10, resulting from the self-coupling,and carbazoles 19-23 have been identified as bmroducts. Ab initio calculations and electrochemical measurements have been employed to acibunt for the observed selectivity.

Introduction Oxidative coupling of 2-naphthol and ita derivatives is a simple and efficient method for the preparation of symmetrically substituted binaphthyls as documentedby numerous examples in the literature.' Thus, for instance, two molecules of a-naphthol(1) can be coupled by means of Cu(II)z-4or other mild oxidants" to produce binaphthol (6) in high yield. Similarly, 2-naphthylamine (2) gives diamine 78 while 4 affords 9.2 By contrast, selective crosscoupling of two different molecules is rare:a1o among the handful of examples is the Cu(I1)-mediatedcoupling 1 + 2 producing 118 and 1 + 4 furnishing 12.1° The symmetrically 2,2'-disubstituted 1,l'-binaphthyls, such as 6 and 7,11have been extremely successful as C2-

symmetric chiral ligands in asymmetric synthesis, with >90% ee achieved being more the rule rather than the exception. Additional substituents at positions 3 and 3' have been recognized to impose further steric interactions, an effect which often results in the remarkable increase of asymmetricinduction.12 In contrast to the wide use of (11) For reviews, see, e.g., ref l g and (a) Morrison, J.
