Magnetic Resonance Spectra

The proton magnetic resonance spectra of various N-nitroso derivatives of sarcosine, L-proline, and iminodiacetic acid, including some protected dipeptides, have been obtained. Magnetic non-equivalence and conformational isomerism arising from restricted rotation of the nitroso group are discussed in relation to the reported behaviour of other nitrosamines. Long-range shielding effects on protons at a considerable distance from the anisotropic nitrosamino centre were readily detected with these compounds.

9-Hydroxy-9-methyl derivatives of the ring systems named in the title are formed along with the expected 1-(o-acetylphenyl)azoles in the Ullmann condensations of o-bromoacetophenone with imidazole and with 1,2,4-triazole. The structures of these compounds follow from their characteristic proton magnetic resonance spectra.
