Compounds of the above structure are potentially close analogs, homo-isosteres, -NOH- replacing -O-, of biochemically important molecules. Under aerobic conditions, solutions of these derivatives contain minute concentrations of the corresponding nitroxide radicals which do not decrease significantly the resolution of the NMR. spectra but render these compounds usable as a new kind of spin labels. Spectroscopic properties (1H-NMR., 13C-NMR., ESR.) of some of these compounds are reported.
