In the title mononuclear complex, [CdCl(2)(C(17)H(11)N(3)O)], the Cd(II) ion assumes a distorted trigonal-bipyramidal coordination geometry. The pyridone plane is twisted out of the 1,10-phenanthroline mean plane by 43.8 (3)°. In the crystal structure, short inter-molecular distances [3.627 (4)-3.671 (4) Å] between the centroids of the six- and five-membered Cd-containing rings suggest the exis...

The title compound, C(12)H(13)NO(2), represents a conformationally restricted 2-pyridone analogue of 1,4-dihydro-pyridine-type calcium antagonists and was selected for a crystal structure determination in order to explore some aspects of drug-receptor inter-action. In the mol-ecule, two stereogenic centres are of opposite chirality, whereas a racemate occurs in the crystal. It was found that th...

The in vivo conversion ratio of N1-methylnicotinamide (NMN) to N1-methyl-2-pyridone-5-carboxamide (2-PY) and N1-methyl-4-pyridone-3-carboxamide (4-PY) as a parameter for the estimation of aldehyde oxidase level in rats was examined. NMN and its pyridones (2-PY and 4-PY) are usually detected in the urine of rats. When we measured the ratio of the amount of pyridones to the total amount of NMN an...

A highly practical and efficient preparation of pyrano[3,2-c]pyridone and pyrano[3,2-c]quinoline derivatives was developed via an ionic liquid mediated and promoted multi-component reaction of malononitrile, aldehyde, and 4-hydroxyquinolin-2(1H)-one or 4-hydroxy-6-methylpyridin-2(1H)-one. The combinatorial syntheses were achieved for the first time without applying extra activation energy at am...

In the title mononuclear complex, [CuCl(2)(C(17)H(11)N(3)O)], the Cu(II) ion is in a distorted square-pyramidal coordination environment. The crystal structure is stabilized by various π-π stacking inter-actions in which the benzene ring, a pyridine ring and the five-membered CuN(2)C(2) ring are involved. The centroid-centroid distances range from 3.5631 (15) to 3.5666 (16) Å.
