HIV-1 integrase catalyzes the insertion of viral DNA into the genome of the host cell. Integrase inhibitor N-(4-fluorobenzyl)-8-hydroxy-1,6-naphthyridine-7-carboxamide selectively inhibits the strand transfer process of integration. 4-Substituted pyrrolidinones possessing various groups on the pyrrolidinone nitrogen were introduced at the 5-position of the naphthyridine scaffold. These analogs exhibit excellent activity against viral replication in a cell-based assay. The preparation of these compounds was enabled by a three-step, two-pot reaction sequence from a common butenolide intermediate. (c) 2008 Elsevier Ltd. All rights reserved.

Supramolecular graft copolymers containing a quadruple hydrogen bond motif in the main chain have been prepared by acyclic diene metathesis (ADMET) polymerization of an alpha,omega-diene monomer containing a 2,7-diamido-1,8-naphthyridine (Napy) unit. During the ADMET polymerization, a supramolecular protection strategy was applied in order to prevent naphthyridine coordination to the ruthenium catalyst. The 2-ureido-4[1H]-pyrimidinone (UPy) derivatives used as protecting groups also allowed for detection of the supramolecular graft copolymer with size exclusion chromatography. Deprotection by simple treatment with a polar solvent afforded free Napy binding sites on the main chain. Reversible grafting of UPy derivatives of various sizes onto the free poly-Napy was demonstrated by diffusion-ordered NMR experiments.

A convenient synthis for 4-substituted and 3,4-disubstituted 1,7-naphthyridine-2(1H)-thiones 7 has been developed. The method is based on the electrocyclic reaction of 4-(1-arylalk-1-enyl)-3-isothiocyanatopyridines 6, generated in situ by the treatment of the respective isocyanides 5 with S8 in the presence of a catalytic amount of selenium. The isocyanides 5 can be easily prepared from commercially available pyridin-3-amine by conventional organic reactions.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 13331-27-6, in my other articles. Recommanded Product: 13331-27-6.

Edges of carbon materials have been known to work as active sites for various applications such as catalysts, adsorbent, and electrodes, but selecting precursors for carbon materials with controlled edges in the absence of metallic substrate is challenging. This work developed a method to select the superior precursors instantaneously using molecular dynamic simulation. This simulation predicted that hydrogen in precursors gasified and the hydrogen attacked the active sites in precursors upon carbonization, causing the decrement of active sites. Thus, it is essential to reduce the concentration of hydrogen in precursors and it is also necessary to introduce reactive functional groups near the active site to protect the active sites. We indeed synthesized the selected precursors such as diethynyl anthracene, diethynyl chrysene, divinyl naphthyridine, and divinyl phenanthroline and proved that edges in those precursors were maintained even after carbonization at 773 K using diffuse reflectance infrared Fourier transform and X-ray photoelectron spectroscopy with the aid of spectra simulated by density functional theory calculation. Especially, ca. 100% of edge structures of zigzag edges and armchair edges in diethynyl anthracene and diethynyl chrysene was maintained even after carbonization at 773 K. (C) 2017 Elsevier Ltd.

Theoretical assessment of TD-DFT applied to a ferrocene-based complex

We present a theoretical study of the electronic absorption spectrum of the 2-ferrocenyl-1,8-naphthyridine (FcNP) complex using the time-dependent density functional theory (TD-DFT) approach. The calculations were carried out at the DFT/LANL2DZ(Fe)/6-31++G(d) level of theory with nine DFT functionals of the type GGA (PBE, B97D), HGGA (B3LYP, PBEO), HMGGA (M05, M06) and range-separated (wB97XD, CAM-B3LYP, LC-wPBE) in the condensed phase (CH2Cl2). The experimental spectrum for FcNP presents three electronic absorption bands (A, B, C) in the UV region and one band (D) in the visible region. We found that there is no unique functional that reproduces the entire electronic spectrum. GGA and LC-wPBE functionals predict large errors (up to 0.57 eV) for the UV bands. On the contrary, HGGA (PBEO), HMGGA (M05, M06) and range-separated (wB97XD, CAM-B3LYP) functionals give small errors for these bands, 0.18, 0.12 and 0.25 eV, respectively. Band D is well described by all the functionals with errors up to 0.26 eV, except by the M05 and M06 functionals, which fail in this region with significant errors (0.52 and 0.56 eV). The analysis of the excitation energies shows that the PBEO, wB97XD and CAM-B3LYP functionals predict the best agreement with the experimental data. The two stronger bands (A, B) in the UV region are assigned to a ligand ligand charge transfer (L-LCT) that involves the Cyclopentadienyl rings (Cp) and the naphthyridine fragment (NP), and then associated with pi -> pi* electronic transitions. The two weaker bands (C, D) are assigned to a charge transfer from ligand (Cp) to metal (Fe)-ligand (NP) (L-MLCT) which is mainly addressed through the dxy and dz(2) atomic orbitals, respectively. No charge transfer is observed between metal and NP ligand. It was shown that the theoretical methods used for understanding the electronic absorption properties of FcNP were adequate because the results showed an excellent agreement with experimental ones.

The title complex, [Ag-4(C7H5O3)(2)(C8H6N2)(4)(C7H6O3)(4)], lies about an inversion centre and has a unique tetranuclear structure consisting of four Ag-I atoms bridged by four N atoms from two 1,8-naphthyridine (napy) ligands to form an N: N’-bridge and four O atoms from two salicylate ( SA) ligands to form an O: O’-bridge. The Ag atoms have distorted octahedral coordination geometry. The centrosymmetric Ag-4 ring has Ag – Ag separations of 2.772 ( 2) and 3.127 ( 2) angstrom, and Ag – Ag – Ag angles of 107.70 ( 4) and 72.30 ( 4) degrees. All SA hydroxy groups take part in intramolecular O – H center dot center dot center dot O hydrogen bonding. In the crystal packing, the napy rings are oriented parallel and overlap one another. These pi-pi interactions, together with weak intermolecular C – H center dot center dot center dot O contacts, stabilize the crystal structure.

Rhenium Complexes with a Pyridinyl-Naphthyridine Ligand: Synthesis, Characterization, and Catalytic Activity

Treatment of [Re2(CO)8(CH3CN)2] with 2,7-dipyridinyl-1,8-naphthyridine (bpnp) thermally provided mononuclear [(N,N-bpnp)Re(CO)3Cl] (1). Further reaction of 1 with rhenium carbonyls yielded ortho-metallation dinuclear rhenium complex 2. Both complexes were characterized by spectroscopic analyses and single-crystal X-ray determination. Complex 1 also reacted with [PdMeCl(COD)] and [Ir(COD)Cl]2 by means of ortho-metallation to yield the corresponding heterodinuclear species. Complex 2 appears to be an excellent precatalyst to promote the insertion of terminal alkynes into acetoacetates, which subsequently undergo cyclization to form 2-pyranones.
