Notes:
Electron spin resonance and ENDOR spectra of semiquinones from daunomycin, adriamycin, their derviatives and model compounds are reported. Hyperfine coupling constants were assigned with the help of TRIPLE resonance and partial deuteration. In contrast to published results, the data obtained were interpreted on the basis of a rapid conformational interconversion of ring A with participation of half chair and boat conformers.
