Intramolecular Heck reaction: A facile sequential one-pot synthesis of 1,2,3,4-tetrahydrobenzo[b][1,6]naphthyridines

A simple and convenient sequential one-pot synthesis of 1,2,3,4-tetrahydrobenzo[b][1,6] naphthyridines has been developed. The reductive amination of 2-chloro-3-formylquinolines with various amines in the presence of sodium borohydride provided the corresponding secondary amines in high yields. Further, a sequential one-pot reaction involving N-allylation and intramolecular Heck type 6-exo-trig cyclization was performed on the secondary amines to afford a range of desired 1,2,3,4-tetrahydrobenzo[b][1,6]naphthyridine derivatives in good to high yields.

Ag(I)-Catalyzed one-pot synthesis of 4-fluorobenzo[b][1,6] naphthyridines and 4-fluoroisoquinolines via iminofluorination of alkynes with Selectfluor

Ag(I)-Catalyzed one-pot synthesis of 4-fluorobenzo[b][1,6] naphthyridines is described from o-alkynyl-quinolinyl aldehydes through imines in good to excellent yields. Selectfluor is used as a fluorinating reagent and the reaction proceeded at room temperature in an open atmosphere. Reactions employed in this synthesis method are also applied for the synthesis of 8-fluoro-1,6-naphthyridine, 7-fluoro-pyrazolo [4,3-c] pyridine and 4-fluoroisoquinoline derivatives. Standardized conditions were also applied on a gram scale reaction and gave a good yield of the product.

Tuning the Bonding of a mu-Mesityl Ligand on Dicopper(I) through a Proton-Responsive Expanded PNNP Pincer Ligand

We report the synthesis and characterization of a series of cationic, neutral, and anionic dicopper(I) complexes featuring a p-mesityl ligand and a naphthyridine-derived PNNP expanded pincer ligand. Structural characterization showed that the protonation state of the dinucleating ligand has a pronounced effect on the bending and tilting of the mu-mesityl ligand. DFT calculations indicate that the varying orientations of the mu-mesityl ligand are inherent due to changes in electronic structure rather than crystal-packing effects. NBO analysis reveals how the interactions that contribute to the three-center two-electron bond between the mu-mesityl ligand and the dicopper core change for the various degrees of observed bending and tilting.

Synthesis, crystal structures, and electronic spectra of (1,8-naphthyridine)Re-I(CO)(3)Cl and [(1,8-naphthyridine)Cu-I(DPEPhos)]PF6

Two 1,8-naphthyridine (nap) metal complexes (nap)Re-I(CO)3CI (1) and [(nap)Cu-I(DPEPhos)]PF6 (2) were synthesized and characterized by NMR-, emission, and absorption spectroscopy, elemental analysis, mass spectrometry, and X-ray structural analysis. In both complexes, the nap ligand coordinates with both N atoms to the metal centre in a bidentate manner. I and 2 exhibit a broad phosphorescence in solid state at T = 300 K, which is completely quenched in solution at r.t. In addition, the gas-phase structures of both complexes were optimized at the B3LYP/6-31G(d,p) level of theory. (c) 2007 Elsevier B.V. All rights reserved.

Biological assays of BF2-naphthyridine compounds: Tyrosinase and acetylcholinesterase activity, CT-DNA and HSA binding property evaluations

The present work reports the biological assays between synthetic BF2-naphtyridine complexes and four proteins: human serum albumin (HSA). calf-thymus DNA (CT-DNA), tyrosinase and acetylcholinesterase enzymes via spectroscopic analysis at physiological conditions, combined with molecular docking simulations. The BF2-complexes presented spontaneous and moderate binding ability to HSA through the ground-state association (static fluorescence quenching mechanism). The main binding site is Sudlow’s site I (subdomain IIA) and the binding does not perturb significantly both secondary and surface structure of HSA. Despite BF2-complexes showed good binding ability with HSA, these compounds presented weak intercalative ability with CT-DNA (the most conventional and simple model to preliminary studies), except in the case of 1 h, which suggested that the presence of electronic donor groups in both aromatic ring moieties of BF2-complex structure can increase the intercalative ability for DNA strands. Competitive binding displacement assays in the presence of methyl green and molecular docking calculations indicated that the studied compounds interact preferentially in the major groove of DNA In addition, the assayed compounds presented the ability to activate or inhibit both tyrosinase (the decontrolled activity can induce melanoma carcinoma) or AChE (involved in reactions related to the function of neurotransmitters) enzymes.

Synthesis and selective colorimetric detection of iodide ion by novel 1,5-naphthyridine-based conjugated polymers

A highly selective colorematric detection of iodie ion based on 1,5-naphthyridine-based conjugated polymers (CPs) is reported. The synthesis of these new conjugated copolymers poly(2-(2-methoxyphenoxy)-6-(3-methoxyphenoxy)-1,5-naphthyridine)-p-bisdodecyloxyphenylene vinylenes) (P1) and poly(2-(2-methoxyphenoxy)-6-(3-methoxyphenoxy)-1,5-naphthyridine)-p-bis-2-(ethyl-hexyloxy)-phenylene vinylenes) (P2) was achieved by the Horner-Emmons polymerization reaction. These polymers were characterized by H-1 NMR, FT-IR and UV-vis spectroscopy and their bandgaps (P1 = 2.35 eV; P2 = 2.25 eV) were determined by cyclic voltammetric measurements. In colorimetric sensing, both these polymers can selectively detect iodide ion in a mixture of water and THE in the presence of a wide range of competing ions including F-, Cl-, Br-, NO3-, CH3COO-, SO4-2, SO3-2, S2O3-2 and CN- and exhibit high sensitivity with LOD of 6.5 and 4.5 ppm, respectively. In the sensing protocol, the addition of aqueous solution of iodide salts to the colorless solution of polymers resulted in bare-eye color change from colorless to yellow, along with concomitant changes in the UV-vis spectra. The time dependent and concentration based studies revealed that P2 was more sensitive and quick in response as compared to P1. (C) 2018 Taiwan Institute of Chemical Engineers.
