Syntheses of all singly labeled [15N]adenines: Mass spectral fragmentation of adenine
AUTOR(ES)
Barrio, Maria Del Carmen G.
RESUMO
Syntheses of all five of the singly labeled [15N]adenines are now provided. The presence or absence of two-bond 15N-1H spin couplings in their 1H NMR spectra confirm the location of the isotope in each case. The fragmentation patterns in their mass spectra are indicative of the sequential losses of HCN units and of CH2N2 from adenine upon electron impact.
