Abstract:
Abstract It is shown by feeding experiments with [3-2H]pyridine-2,6 -dicarboxylic acid that 6 -(hydroxythio)carbonylpyridine-2-carboxylic acid and pyridine-2 -carboxylic acid-6-m onothiocarboxylic acid are intermediates in the biosynthesis of pyridine-2,6 -di(monothiocarboxylic acid) from pyridine-2,6 -dicarboxylic acid produced by Pseudomonas putida. Thus the series of biosynthetic steps - COOH → - CO - SOH → COSH has been demonstrated for the first time.

Abstract:
Molecular adducts of urea with six aromatic carboxylic acids have been prepared and characterized by using X-ray diffraction methods and infrared spectroscopy. These compounds are with 5-nitrosalicylic acid [(C7H5NO5)2(CH4N2O)] (1), 3,5-dinitrosalicylic acid [(C7H4N2O7)(CH4N2O)] (2), 4-aminobenzoic acid [(C7H7NO2)2(CH4N2O)] (3), o-phthalic acid [(C8H6O4)(CH4N2O)] (4), pyrazine-2,3-dicarboxylic acid [(C4H4N2O4)(CH4N2O)] (5) and pyridine-2,6-dicarboxylic acid [(C7H5NO4)(CH4N2O)2] (6). In the majority of the adducts, all six potential interactive sites on the urea molecules are utilized in hydrog

Abstract:
The design and synthesis of 3d–4f heterometallic coordination polymers have attracted much interest due to the intriguing diversity of their architectures and topologies. Pyridine-2,6-dicarboxylic acid (H2pydc) has a versatile coordination mode and has been used to construct multinuclear and heterometallic compounds. Two isostructural centrosymmetric 3d–4f coordination compounds constructed from pyridine-2,6-dicarboxylic acid and 4,4′-bipyridine (bpy), namely 4,4′-bipyridine-1,1′-diium diaquabis(μ2-pyridine-2,6-dicarboxylato)tetrakis(pyridine-2,6-dicarboxylato)bis[4-(pyridin-4-yl)pyridinium]co

Pyridine-3,5-dicarboxylic acid has been studied by single-crystal neutron diffraction at 15 and 296 K. Pyridine-3,5-dicarboxylic acid, in which the carboxylic acid protons have been replaced by deuterons, has also been studied at 15, 150 and 296 K. The protonated structure contains a short N...H...O hydrogen bond [N...O 2.523 (2) Å at 15 K]. Temperature-dependent proton migration occurs where the N—H distance in the hydrogen bond changes from 1.213 (4) Å at 15 K to 1.308 (6) Å at 300 K. In the deuterated structure the overall hydrogen-bond length increased [N...O 2.538 (3) Å at 15 K] and the m

The acid formed upon ester hydrolysis, hydrogen 2-[N-(2′-pyridylmethyl)carbamyl]pyridine-6-carboxylate (H22), has been isolated

9a A series of linear and macrocyclic pentapeptide derivatives have been prepared via the coupling of pyridine-2,6-dicarboxylic acid (1) or pyridine-2,6-dicarbonyl dichloride (2) with appropriate amino acid methyl esters. The coupling of 1or 2with aminoacid methyl esters gave the corresponding pyridine dipeptide methyl esters 3, which were hydrolyzed with sodium hydroxide to the corresponding acids 4. The latter compounds 4were coupled with other amino acid methyl esters to afford the corresponding tetrapeptide esters 5, which were hydrolyzed with sodium hydroxide to the corresponding acids 6.
