5-Ethyl-6-methyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (cas: 39083-15-3) belongs to pyrimidine derivatives. Pyrimidines are isomeric with two other forms of diazines: pyridazine, with the nitrogen atoms in the 1 and 2 positions; and pyrazine, with the nitrogen atoms in the 1 and 4 positions. A Cu-catalyzed and 4-HO-TEMPO-mediated [3 + 3] annulation of commercially available amidines with saturated ketones enables an efficient and facile synthesis of structurally important pyrimidines via a cascade reaction of oxidative dehydrogenation/annulation/oxidative aromatization.Category: pyrimidines
Solid phase synthesis of 5,6-disubstituted pyrimidinone and pyrimidindione derivatives was written by Parlato, Maria cristina;Mugnaini, Claudia;Renzulli, Michela Lucia;Corelli, Federico;Botta, Maurizio. And the article was included in ARKIVOC (Gainesville, FL, United States) in 2004.Category: pyrimidines The following contents are mentioned in the article:
Solid phase synthesis of 5,6-disubstituted pyrimidinone and pyrimidindione derivatives, e.g. I and II, were prepared, in 88 and 85% yield, by condensing polymer bound thiouronium salts with β-ketoesters, e.g. Et acetoacetate, and cleavage of the product with TFA and Oxone/H2O/dioxane, resp. Combinatorial libraries of pyrimidindiones, 2-thiopyrimidinones, and 2-methoxypyrimidinones were generated by using a Syncore Reactor. This study involved multiple reactions and reactants, such as 5-Ethyl-6-methyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (cas: 39083-15-3Category: pyrimidines).
