In the title compound, C(26)H(20)O(4), the complete molecule is generated by a crystallographic 2-fold axis and the naphthalene ring system is planar within 0.05 (4) Å. The dihedral angles between the -COO plane, the benzene ring and naphthalene ring system are 12.83 (3) and 12.93 (1)°, respectively. The -COO plane and the benzene ring are almost coplanar, forming a dihedral angle of 2.59 (8)°.

In the title compound C(25)H(18)O(3), the central benzene ring forms dihedral angles of 87.4 (5) and 85.4 (4)° with the phenyl ring and the naphthalene ring system, respectively. The carbonyl O atoms deviate significantly from the phenyl ring and the meth-oxy-substituted naphthalene ring system [by 0.508 (1) and 0.821 (1) Å, respectively]. The crystal packing is stabilized by C-H⋯O hydrogen bon...

In the title mol-ecule, C(22)H(16)N(2)O, the phenyl ring is twisted slightly with respect to the plane of the central pyrazole ring [dihedral angle = 14.8 (2)°]; the central ring is connected to the naphthyl ring through a -CH=CH-C(=O)- fragment, whose C=C double bond has an E configuration. The pyrazole ring and naphthalene ring system are twisted by 46.3 (1)°. Weak inter-molecular C-H⋯O hydro...

We report direct arylation of arylhalides with unactivated sp2 C-H bonds in benzene and naphthalene using a copper(I) catalyst featuring an ambiphilic ligand, (quinolin-8-yl)dimesitylborane. Direct arylation could be achieved with 0.2 mol % catalyst and 3 equivalents of base (KO(t-Bu)) at 80 °C to afford TON ≈160-190 over 40 hours.

Herein we describe the synthesis and HIV-1 protease (PR) inhibitory activity of 16 new peptidomimetic molecular tongs with a naphthalene scaffold. Their peptidic character was progressively decreased. Two of these molecules exhibited the best dimerization inhibition activity toward HIV-1 wild-type and multimutated ANAM-11 proteases obtained to date for this class of molecules (∼40 nM for wild-t...
