摘要:

13C NMR parameters have been obtained for vicine and convicine in DMSO, D2O/DMSO and D2O. Complete assignment of the spectra has been achieved. Interpretation of spin-lattice relaxation rates and heteronu-clear NOES has yielded evidence of intramolecular structuring in the case of vicine and not in that of ronvirine and also of a complex network of solute-solvent interactions.
