A new series of Et 5-substituted 2,3-dihydro-3-oxoisothiazolo[5,4-b]pyridine-2-acetate I (R = NH2, Me, Ph, H, NO2) was prepared either a) directly by reaction of 5-substituted 2-chlorothio-3-pyridinecarbonyl chlorides with Et glycine or b) by oxidation of the corresponding 2-mercapto-3-pyridinecarboxamides. Some reactions of the free acids of I as starting materials are described. The experimental process involved the reaction of 2-Oxo-5-phenyl-1,2-dihydropyridine-3-carboxylic acid(cas: 10177-08-9Application of 10177-08-9)
2-Oxo-5-phenyl-1,2-dihydropyridine-3-carboxylic acid(cas: 10177-08-9) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. Application of 10177-08-9 Pyridine has a conjugated system of six π electrons that are delocalized over the ring.
