Crystal Chemistry of Zinc Quinaldinate Complexes with Pyridine-Based Ligands
Substitution of methanol in [Zn(quin)2(CH3OH)2] (quin− denotes an anionic form of quinoline-2-carboxylic acid, also known as quinaldinic acid) with pyridine (Py) or its substituted derivatives, 3,5-lutidine (3,5-Lut), nicotinamide (Nia), 3 ...

An overview of synthesis and biological activities of 2-pyridone derivatives over the last decade
2-Pyridone frameworks are a pervasive member of the N-heterocyclic family of both chemical and therapeutic interest. 2-Pyridones and their bridged analogues have wide occurrences in nature and the presence of both aromatic and amide groups in the ...

2-Pyridone: monoclinic polymorph
The asymmetric unit in the title compound, C5H5NO, comprises two independent but virtually identical molecules of 2-pyridone, and represents a monoclinic polymorph of the previously reported orthorhombic (P212121) form [Penfold (1953). Acta Cryst. 6, 591&

Pyridone-based nucleotide analogues accepted for DNA biosynthesis
Novel pyridone-based nucleotides were investigated for maintenance of DNA synthesis, carried on by representatives of different classes of polymerases. Five different nucleoside triphosphates of similar structure were addressed, demonstrating involvement

Total synthesis of (−)-epimyrtine by a gold-catalyzed hydroamination approach
A new approach to the total synthesis of (−)-epimyrtine has been developed from D-alanine. The key step to access the enantiopure pyridone intermediate was achieved by a gold-mediated cyclization.
