Abstract:

Proton and nitrogen-15 magnetic resonance spectra of several derivatives of pyrimidine have been studied. Long-range 15N-H couplings were observed in uracil-15N2, 2,4-dichloropyrimidine-15N2, 2,4-dimethoxypyrimidine-15N2, 1-methyl-4-methoxy-2-pyrimidone-15N2, and 1-methylcytosine-15N3. A particularly large 15N1-C-H coupling 12.5 c.p.s. has been observed in 2,4-dichloropyrimidine-15N2. 1-Methylcytosine-15N3 has been shown to exist in the amino tautomeric form and to protonate at N3 in agreement with previously reported work on 1-methylcytosine labeled only in the amino group.
