Synthesis and spectroscopic properties of novel polyfunctionally substituted 2,6-and 2,7-naphthyridines

Series of 5,6-dihydro-8-hydroxy-5-oxo-2,6-naphthyridine-7-carboxylic acid derivatives (2,4) and the isomeric 7,8-dihydro-5-hydroxy-8-oxo-2,7-naphthyridine-6-carboxylic acid derivatives (3,5) having potential pharmacological activity were synthesized from 3,4-pyridinedicarboxylic acid derivatives.

One-Pot Synthesis of Densely Substituted 1,2,3,4-Tetrahydro-1,6-naphthyridine Mediated by Isocyanide-Assisted Reduction of C-C Double Bond

Molecular architectures possessing the combination of heteroaromatic and saturated N-heterocycles are of great importance because of their higher solubility in the gastrointestinal tract due to weak crystal packing in the three-dimensional structure. Other biological activity like selectivity is also increased in a positive way. However, compared to fully aromatic fused heterocycles, synthesis of partially saturated fused heterocycles is much more difficult since the later needs greater control over the reaction conditions. In this context, 1,2,3,4-tetrahydronaphthyridines (THNADs) are essential part of pharmaceutically important natural products and drug molecules. However, the synthesis of THNAD is seldom reported in literature. To the best of our knowledge, this is the first report of metal-free one pot synthesis of 1,2,3,4-tetrahydro-1,6-naphthyridines without starting from any nitrogen heterocycles in water. Moreover, this study discloses the involvement of isocyanide in a chemical reaction whose net effect is only to reduce a C=C bond which is unusual in isocyanide literature.

Synthesis and characterization of ruthenium (II) carbonyl complexes containing naphthyridine and acetylacetonate ligands and their catalytic activity in the hydrogen transfer reaction

A series of novel complexes of the Ru(L)(2)(CO)(2) L = 2-(3′ methoxyphenyl)-1,8-naphthyridine (complex 1), and type Ru(acac)(2)(L)(CO) with L = 2-(3′ methoxyphenyl)-1,8-naphthyridine (complex 2), 2-(2′-bromophenyl)-1,8-naphthyridine (complex 3) and 2-phenyl-1,8-naphthyridine (complex 4) was synthesized and characterized. We found that the complexes 2, 3, and 4 can be directly synthesized from Ru-3(CO)(12). The complex Ru(acac)(2)(L)(CO) L = 2-(3′ methoxyphenyl)-1,8-naphthyridine (2) was characterized by X-ray single crystal analysis which confirms the monodentate coordination mode of the 1,8-naphthyridine derivate and the cis arrangement of the acac ligands. Preliminary studies in transfer hydrogenation of acetophenone in the presence of 2-propanol show the good catalytic activity of complex 2 with 92% conversion. (C) 2012 Elsevier B.V.

Palladium complexes with an annellated mesoionic carbene (MIC) ligand: catalytic sequential Sonogashira coupling/cyclization reaction for one-pot synthesis of benzofuran, indole, isocoumarin and isoquinolone derivatives

Two Pd(II) complexes (1 and 2) featuring a fused pi-conjugated imidazo[1,2-a][1,8]naphthyridine-based mesoionic carbene ligand have been synthesized and structurally characterized. Both complexes effectively catalyze the one-pot synthesis of benzofuran starting from phenylacetylene and 2-iodophenol under mild conditions. Complex 1 is found to be an excellent catalyst for the straightforward access to a library of benzofuran, indole, isocoumarin and isoquinolone derivatives by the reaction of terminal alkynes with 2-iodo derivates of phenol, N-methyl aniline, benzoic acid and N-methyl benzamide, respectively. The general utility of the catalytic method is demonstrated using a variety of diversely substituted terminal alkynes and the corresponding desired products are obtained in good to excellent yields. On the basis of control experiments, a two-cycle mechanism is proposed which involves the Sonogashira coupling of 2-iodo derivatives with alkynes and the subsequent cyclization of the corresponding 2-alkynyl compounds.

1,8-Naphthyridines VIII. Novel 5-aminoimidazo[1,2-a] [1,8]naphthyridine-6-carboxamide and 5-amino[1,2,4]triazolo[4,3-a] [1,8]naphthyridine-6-carboxamide derivatives showing potent analgesic or anti-inflammatory activity, respectively, and completely devoid of acute gastrolesivity

On the basis of the very interesting pharmacological properties shown by the 5-amino[1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamide derivatives 1, previously described by us, we have now prepared the 5-aminoimidazo[1,2-a][1,8]naphthyridine-6-carboxamide derivatives 2a-o (a new structural class) whose tricyclic system is isosteric to that of compounds 1. Both compounds 2 and some new properly substituted compounds 1 (1f-k) now synthesized were tested in vivo for their analgesic and anti-inflammatory activities: on the whole, compounds 2 showed notable analgesic properties, whereas many compounds 1 exhibited a very potent anti-inflammatory activity, coupled to scarce analgesic activity. All the effective compounds proved to be completely devoid of acute gastrolesivity (gastric damage) in rats (at the 200 mg kg(-1) oral dose). (C) 2009 Elsevier Masson SAS. All rights reserved.

Silica Gel-Catalyzed One-Pot Syntheses in Water and Fluorescence Properties Studies of 5-Amino-2-aryl-3H-chromeno[4,3,2-de][1,6]naphthyridine-4-carbonitriles and 5-Amino-2-aryl-3H-quinolino[4,3,2-de][1,6]naphthyridine-4-carbonitriles

The silica get-catalyzed synthesis of 5-amino-2-aryl-3H-chromeno[4,3,2-de][1,6]naphthyridine-4-carbonitriles and 5-amino-2-aryl-3H-quinolino[4,3,2-de][1,6]naphthyidine-4-carbonitriles were simply achieved upon the one-pot cascade reaction of malononitrile with Substituted 2-hydroxyacetophenone (or 2-aminoacetophenone) and aromatic aldehyde in aqueous media. The mechanistic investigation results based on electrospray ionization mass spectrometry (ESI-MS) indicated that malononitrile displayed a dual role during this transformation. Thirteen bonds were cleaved and 12 new bonds were constructed in the formation of 5-amino2-aryl-3H-chromeno[4,3,2-de][1,6]naphthyridine-4-carbonitriles, while only 2 H2O molecules were removed. The fluorescence properties screening showed five new compounds have high fluorescence quantum yields.

Enhancement of affinity in molecular recognition via hydrogen bonds by POSS-core dendrimer and its application for selective complex formation between guanosine triphosphate and 1,8-naphthyridine derivatives

We report that a polyhedral oligomeric silsesquioxane (POSS) core in a dendrimer can enhance the affinity of the molecular recognition via hydrogen bonds between 1,8-naphthyridine and guanosine nucleotides. The complexation of the naphthyridine ligands with a series of guanosine nucleotides was investigated, and it is shown that the POSS core should play a significant role in the stabilization of the complexes via hydrogen bonds. Finally, we demonstrate that the 1,8-naphthyridine ligand can selectively recognize guanosine triphosphate by assisting with the POSS-core dendrimer.
