A challenging direct asymmetric catalytic aerobic oxidative cross-coupling of 2-naphthylamine and 2-naphthol, using a novel CuI/SPDO system, has been successfully developed for the first time. Enantioenriched 3,3′-disubstituted NOBINs were achieved and could be readily derived to divergent chiral ligands and catalysts. This reaction features high enantioselectivities (up to 96 % ee) and good yields (up to 80 %). The DFT calculations suggest that the F–H interactions between CF3 of L17 and H-1,8 of 2-naphthol, and the π–π stacking between the two coupling partners could play vital roles in the enantiocontrol of this cross-coupling reaction.

Metalation of 2-heterosubstituted naphthalenes at the 1- or 3- position: Factors that may determine the regiochemistry
Ruzziconi, Renzo,Spizzichino, Sara,Giurg, Miroslav,Castagnetti, Eva,Schlosser, Manfred
experimental part, p. 1531 - 1535 (2010/10/20)
Upon metalation and subsequent electrophilic trapping, 2-fluoronaphthalene inevitably gives rise to regioisomeric mixtures in varying proportions, whereas 2-(trifluoromethyl)naphthalene undergoes deprotonation either at the 1- or the 3-position, depending on the choice of the reagent. On the other hand, 2-(trifluo-romethoxy)naphthalene and 2-methoxynaphthalene react exclusively at the 3-position when, respectively, sec-butylhthium and superbasic reagents are employed. Steric repulsion by the peri hydrogen in combination with crowding due to coordination of the lithium atom with the methoxy group disfavors attack at the 1-position. Georg Thieme Verlag Stuttgart.

Synthesis and structural analysis of oligo(naphthalene-2,3-diyl)s
Motomura, Takahisa,Nakamura, Hideko,Suginome, Michinori,Murakami, Masahiro,Ito, Yoshihiko
, p. 142 - 146 (2007/10/03)
Oligo(naphthalene-2,3-diyl)s are synthesized by the palladium-catalyzed cross-coupling reactions of 2-naphthyl-zinc compounds with 2-bromonaphthalene derivatives. An NMR analysis together with an X-ray diffraction study supports the conjecture that the helical secondary structure is a common feature of the assemblies in which naphthalene-like aromatic units are linked together between the β-positions in series.
