Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1194-22-5, is researched, SMILESS is CC1=NC(=CC(N1)=O)O, Molecular C5H6N2O2Journal, Journal of Physical Chemistry called Reactions of oxidizing radicals with 4,6-dihydroxypyrimidines as model compounds for uracil, thymine, and cytosine, Author is Novais, H. M.; Steenken, S., the main research direction is radical oxidizing reaction pyrimidinediol.Recommanded Product: 6-Hydroxy-2-methylpyrimidin-4(3H)-one.
The reactions of the oxidizing radicals OH, O-, SO4-, and Br2- with 4,6-dihydroxypyrimidine (4,6-DHP) and with 2- and 5-methyl-4,6-DHP were examined by using in situ radiolysis and photolysis ESR and pulse radiolysis techniques. At pH 1-6 the OH radical reacts with these compounds [k = (4-7) × 109 M-1 s-1] selectively by addition at C-5 to produce radicals characterized by two pairs of magnetically equivalent nitrogens and exchangeable protons. On the basis of the coupling constants and from the increased pKa value (8.3) of the radical from 4,6-DHP relative to that (5.3) of the parent compound, a diketo-type structure is suggested for the OH adducts. At pH 8-12 a base-catalyzed dehydration of the radical anions takes place which leads to species formally derived from the ionized parent compound by one-electron oxidation, followed by deprotonation. These radicals can also be produced by reaction with SO4- or Br2-. Those from 4,6-DHP and from 2-Me-4,6-DHP were seen in two different protonation states: as a neutral radical between pH 3 and 5, and as the radical anion above pH ≈ 5. Me groups on the 4,6-DHP mol. increase the rate of dehydration of the OH adducts. The O- radical reacts with the methylated 4,6-DHP’s by H abstraction from the Me groups. The structures of all the radicals from the 4,6-DHP’s are compared with those form naturally occurring dioxopyrimidines such as the uracils.
