[Abstract]:Pyridinone compounds and their derivatives have become a hot research area in the field of medicine, pesticide and chemistry because of their good pharmacology and biological activity. Pharmacological studies have shown that these compounds have been widely used in medical research because of their good anti-tumor, anti-Alzheimer disease AD-Alzheimer disease, that is, Alzheimer's disease, antibacterial, anti-virus, anti-parasitic and anti-liver fibrosis and other biological activities. In addition, with the development of functional materials in recent years, pyridone and its derivatives have been widely used in dyes, thermochromic materials and photosensitive materials. Thiazole ring is a class of quaternary heterocyclic compounds containing Nu S hetero atoms. A large number of literatures show that the compounds with thiazolium heterocyclic structure also have good biological activity, and their special structure makes them useful in the fields of organic synthesis reagents, medicine, green pesticides, rubber accelerators and dyes. Based on the principle of drug superposition, twelve novel 5-azole-6-disubstituted -3-trimethyl-4-methyl-5-acetylthiazole-2-yl) pyridine-2-biaminopyridyl compounds were synthesized by combining thiazolyl ring with pyridinone, and the synthetic conditions were optimized. Thus, the optimal synthetic conditions are obtained. The structure of the synthesized 5o 6-disubstituted -3-methyl-5-acetylthiazole-2-yl) aminopyridine 2-one compounds was characterized by IR 1H NMR-13C NMRMS, and the structure of the synthesized compounds was characterized by IR 1H NMR-13C NMRMS, and the structure of the compounds was characterized by IR 1H NMR-13C NMRMS. At the same time, the antitumor biological activity of 5o 6-disubstituted-3-o-4-methyl-5-acetyl-thiazolyl)-2-bibiaminopyridine-2-one compounds was also studied. The results of the study are as follows: 1. Using 2o 3-dihydroxy pyridine and aniline dihydroxypyridine with different substituents as raw materials, the oxidation-Michael addition method was used. Twelve intermediates, 5o 6-disubstituted -2o 3-pyridine diketone 1, were synthesized, and their structures were characterized. The results were in agreement with the reference value of .2.The reaction of 5o 6-disubstituted -2-pyridine-3-pyridine-1 with thiosemicarbazone was carried out under the catalysis of concentrated sulfuric acid. Twelve intermediates, 5o 6-disubstituted -2pyridine-3-pyridinone thiosemicarbazone derivatives, were synthesized, and their structures were characterized. The results were in agreement with the results in literature. The results were in agreement with the results in the presence of acetic acid in the presence of glacial acetic acid. In this paper, the target product, 5o 6-disubstituted -3-methyl-5-acetylthiazole-2-yl) -2-biaminopyridine-3-one, was synthesized by the reaction of 2-thiosemicarbazone derivative 2 with 3-chloro-2-pyridine-4-pentanedione. The optimum conditions for the synthesis of the target compound 5o 6-disubstituted -3-thiazolyl 4-methyl-5-acetylthiazole-2-yl) pyridine-2-one were obtained, and the appropriate mass ratio, reaction time, reaction temperature, catalyst selection and dosage were obtained. That is, using anhydrous ethanol as a solvent, The molar ratio of material is 1: 2.0, the amount of acetic acid is 0.30 mL, the reaction time is 3.5hourling, the reaction temperature is 65 鈩,
