In Plane Vibration of Pyrimidine and some Deuterated Pyrimidines [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1991
On the basis of 102 assigned frequencies to in plane vibrations of pyrimidine, pyrimidine-2-d2, pyrimidine-2, 5-d2, pyrimidine-4,6-d2, pyrimidine-2,4,6-d3 and pyrimidine-d4, 35 valance force field constants including 14 principals and 21 interaction force constants are calculated.

Studies on the Physiology of Pyrimidines. The Metabolism of the Pyrimidine Nucleosides

open access: yesExperimental Biology and Medicine, 1929
The results of previous work by one of us1 indicated that the pyrimidines uracil and thymine, when fed in small amounts to dogs, are to a large extent metabolized. In the case of cytosine it was found that this substance was not utilized. It was partly excreted unchanged, partly deaminized and excreted in the form of uracil.These experiments were ...

Pyrimidines. XIII. Novel pyrimidine to pyrimidine transformation reactions

Journal of Heterocyclic Chemistry, 1977
AbstractNovel pyrimidine to pyrimidine transformation reactions are described. 1,3‐Dimethyl‐(or diethyl)‐uracil(1) are converted into isocytosine, 2‐thiouracil or uracil derivatives by treatment with guanidine, thiourea or urea, respectively. The latter two cases require base catalysis. The effects of some substituents at C‐5 and C‐6 of 1,3‐dialkylated

The Auger spectroscopy of pyrimidine and halogen-substituted pyrimidines

The Journal of Chemical Physics, 2008
The C 1s and N 1s Auger spectra of pyrimidine, 2-chloropyrimidine, and 5-bromopyrimidine have been measured in an electron impact experiment at 1000 eV. In the case of the halogen-substituted pyrimidines, also the Cl 2p and Br 3d Auger spectra have been recorded.
