Nitrogen-15 Magnetic Resonance Spectroscopy. VI. Pyrimidine Derivatives

Creators

Abstract

Proton and nitrogen-15 magnetic resonance spectra of several derivatives of pyrimidine have been studied. Long-range ^(15)N-H couplings were observed in uracil- ^(15)N_2, 2,4-dichloropyrimidine-^(15)N_2, 2,4-dimethoxypyrimidine- ^(15)N_2, 1-methyl-4-methoxy-2-pyrimidone ^(15)-N_2, and 1-methylcytosine-^(15)N_2. A particularly large ^(15)N_(1)-C-H coupling (12.5 c.p.s.) has been observed in 2,4-dichloropyrimidine-^(15)N_2. 1-Methylcytosine-^(15)N_2 has been shown to protonate at N_(3) in agreement with previously reported work on 1-methylcytosine labeled only in the amino group.
