Cytochrome P-450 (P-450)-catalyzed oxidation of 2,6-dimethyl-4-phenyl-3,5-pyridinedicarboxylic acid diethyl ester gives rise to 2,6-dimethyl-4-phenyl-3,5-pyridinedicarboxylic acid monoethyl ester and to 2-hydroxymethyl-6-methyl-4-phenyl-3,5-pyridinedicarboxylic acid diethyl ester, identified in this work. A pyridine hydroxymethyl diester of the sort of the latter compound is novel; under acidic...

Self-assembly under hydrothermal conditions has been employed to synthesize several novel uranium-containing polymeric materials in the pyridinedicarboxylic acid (pydc) system. Uranium containing coordination polymers were synthesized utilizing 2,3-pyridinedicarboxylic acid (2,3-pydc), 2,4-pyridinedicarboxylic acid (2,4-pydc) and 2,6-pyridinedicarboxylic acid (2,6-pydc) as the organic linker. F...

Two calcium coordination compounds [Ca(2,6-Hpdc)2(H2O)2] 1 and [Ca2(2,3-pdc)2(H2O)6]n 2 (where 2,6-H2pdc = 2,6-pyridinedicarboxylic acid 2,3-H2pdc 2,3-pyridinedicarboxylic acid) were grown at room temperature. The characterized using elemental analysis, Fourier transform infrared (FTIR) spectroscopy, thermogravimetric powder X-ray diffraction single crystal crystallographic analysis. structures...

The reaction of 3-(2,4-dicarboxyphenyl)-2,6-pyridinedicarboxylic acid (H4dppd) with rare earth nitrates under hydrothermal conditions generated a series of new two-dimensional (2D) coordination polymers, namely {[La(Hdppd)(H2O)2·(H2O)2]n (1), [Ln2(Hdppd)2(H2O)4·(H2O)3]n [Ln = Sm (2), Eu (3)] and [Ln(Hdppd)(H2O)3·H2O]n [Ln = Gd (4), Tb (5), Dy (6), Ho (7), Er (8)] [Hdppd = 3-(2,4-dicarboxyphenyl...

The reaction of barium chloride with 2, 6-pyridinedicarboxylic acid in water led to the formation of a novelpolymeric complex formulated as {[Ba2(Hpydc)2(pydc)(H20)3].H20.(H2pydc)}.(I). The crystal structure of (I)was characterized by single crystal X-ray diffraction method. The complex was crystallized in the monoclinicsystem with space group P2/c, with four molecule in unit-cell, e.g Z=4. The...

We unveil a new homogeneous assay-using mercaptopropionic acid-modified Au nanoparticles in the presence of 2,6-pyridinedicarboxylic acid for the highly selective and sensitive detection of Hg(2+) ions.

New acetylenic nematicidal compound, penipratynolene (1), methy (2'R)-4-(2'-hydroxy-3'-butynoxy)benzoate, together with two known compounds, 6-methoxycarbonylpicolinic acid (2) and 2,6-pyridinedicarboxylic acid (3), were isolated from the culture filtrate of Penicillium bilaiae Chalabuda. The structures of 1-3 were established by spectroscopic methods. The absolute configuration of 1 was confir...

The title compound, pyridine-2,4-dicarboxylic acid-S-serine (1/1), C(7)H(5)NO(4)·C(3)H(7)NO(3), has serine in its zwitterionic form. The crystal structure is stabilized by an extensive series of inter-molecular O-H⋯O, N-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional network.
