Rare-Earth-Metal-Catalyzed Synthesis of Azaindolines and Naphthyridines via C-H Cyclization of Functionalized Pyridines

We report herein a rare-earth-metal-catalyzed insertion of a 2-pyridine C(sp(2))-H bond into an intramolecular unactivated vinyl bond. This reaction provides streamlined access to a range of azaindolines in moderate to excellent yields. The salient features of this reaction include simple and mild reaction conditions, 100% atom efficiency, and wide substrate scope. This methodology is also used to construct other nitrogen-containing compounds such as naphthyridine derivatives. A plausible mechanism for the formation of azaindolines involving initial C-H bond activation by the lanthanide complex followed by C=C insertion into a Ln-C bond to form an alkyl lanthanide species that subsequently undergoes cyclization is proposed.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1118-61-2 is helpful to your research. Recommanded Product: 3-Aminocrotononitrile.

Catalytic Conversion of Alcohols to Carboxylic Acid Salts and Hydrogen with Alkaline Water

A [RuH(CO)(py-NP)(PPh3)(2)]Cl (1) catalyst is found to be effective for catalytic transformation of primary alcohols, including amino alcohols, to the corresponding carboxylic acid salts and two molecules of hydrogen with alkaline water. The reaction proceeds via acceptorless dehydrogenation of alcohol, followed by a fast hydroxide/water attack to the metal-bound aldehyde. A pyridyl-type nitrogen in the ligand architecture seems to accelerate the reaction.

Dinuclear and Trinuclear Complexes of Copper(I) and Silver(I) Supported by a Highly Fluorinated Pyrazolate [3,5-(CF3)(2)Pz](-) and N-Heterocycles

The chemistry of trinuclear silver(I) and copper(I) pyrazolates with aromatic, bidentate N-heterocycles, 2,2 ‘-bipyridine, 6,6 ‘-dimethyl-2,2 ‘-bipyridine, 1,10-phenanthroline, 2,9-dimethyl-1,10-phenanthroline, and 1,8-naphthyridine are presented. These N-donor ligands react readily with {[3,5-(CF3)(2)Pz]Ag}(3) and {[3,5-(CF3)(2)Pz]Cu}(3) providing mixed-ligand complexes with all nitrogen coordination spheres at metal in high yield. The fluorinated pyrazolate acts as a bridging ligand in these complexes. The bipyridine and phenanthroline systems with donor lone pairs at an acute angle serve as bidentate chelators for copper and silver providing dinuclear complexes. They feature planar, boat or chair shaped Ag2N4 or Cu2N4 cores and four-coordinate, tetrahedral metal sites. The 1,8-naphthyridine that has donor nitrogen lone pairs at a parallel orientation affords trinuclear copper and silver complexes with two- and three-coordinate metal centers. It uses only one of its lone pairs effectively in these adducts for metal ion coordination. In addition, 1,8-naphthyridine moieties of these copper and silver complexes show intermolecular pi-pi stacking. Results presented here show the effects of donor nitrogen lone-pair orientations of the bidentate N-heterocycles on the structures of the products resulting from their chemistry with {[3,5-(CF3)(2)Pz]Ag}(3) and {[3,5-(CF3)(2)Pz]Cu}(3).

1,8-Naphthyridines IX. Potent anti-inflammatory and/or analgesic activity of a new group of substituted 5-amino[1,2,4]triazolo[4,3-a] [1,8] naphthyridine-6-carboxamides, of some their Mannich base derivatives and of one novel substituted 5-amino-10-oxo-10H-pyrimido[1,2-a][1,8]naphthyridine-6-carboxamide derivative

A new group of 5-(alkylamino)-9-isopropyl[1,2,4]triazolo[4,3-a][1,8]naphthyridine derivatives bearing a CONHR group at the 6-position (1c-g), designed to obtain new effective analgesic and/or anti-inflammatory agents, were synthesized and tested along with three new 9-alkyl-5-(4-alkyl-1-piperazinyl)-N,N-diethyl [1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamides (2b-d). Besides, a new class of analogues of compounds 1 and 2, bearing a Mannich base moiety at the 9-position (12a-d), as well as the novel N,N-diethyl-5-(isobutylamino)-8-methyl-10-oxo-10H-pyrimido[1,2-a][1,8]naphthyridine-6-carboxamide (15) were prepared and tested. Compounds 1c-g exhibited very interesting anti-inflammatory properties in rats, whereas compounds 2b-d and 15 proved to be endowed with prevalent analgesic activity frequently associated with sedative effects in mice. On the contrary, the Mannich bases 12a-d resulted inactive. The most effective (80% inhibition of oedema) and potent (threshold dose 1.6 mg kg(-1) with 31% inhibition of oedema) anti-inflammatory compound 1d did not show gastrolesive effects following 100 mg kg(-1) oral administration in rats.

Synthesis, Biological Evaluation and Molecular Docking Studies of Novel 1,8-Naphthyridine-3-carboxylic Acid Derivatives as Potential Antimicrobial Agents (Part-1)

Synthesis and investigation of antimicrobial activity of 6 novel 1,8-naphthyridine-3-carboxylic acid derivatives are presented. Among the derivatives, compounds 4a-5b2 showed a broad-spectrum antimicrobial activity against all reference Gram-positive, Gram-negative bacteria and fungi. These compounds exhibited remarkable bactericidal activity against Staphylococcus and Bacillus sps. The tested substances 4a-5b2 were found also found to be active against Escherichia coli, Salmonella and Shigella sps. The chlorine substituted compounds 4a and 5a2 were found to be the most active towards the tested microorganisms. Compounds 4a-5b2 were found to be fungicidal against Candida sp. with a MIC values in the range of 400-2000 mu g/ml. Docking studies of these compounds with Salmonella typhi OmpF complexed with ciprofloxacin using PDB-4KRA revealed that the compounds acted as covalent crosslinker on the DNA gyrase B of the former and intercalate the latter both with higher C score values. Thus, the antibacterial activity against tested strains suggested 1,8-naphthyridine-3-carboxylic acid derivatives warrant further evaluation as potential novel antiinfective agents. The antifungal activity of these compounds was comparable to that of griseofulvin. The drug-likeness data of synthesized compounds made them promising leads for the future development as antifungal agents.
