C, 1H NMR spectra for the MeO-PEGN-Succ-RSV conjugate mixture in d 6-DMSO, recorded at 400 MHz. B, The down field region of the 1H NMR spectra (400 MHz) for: (a) a solution of the resveratrol-PEG conjugate mixture in d 6-DMSO showing the assigned signals for the two major products 4'-MeO-PEGN-Succ-RSV and 3-MeO-PEGN-Succ-RSV and (b) a solution of resveratrol in d 6-DMSO. To identify the low intensity down-field signals the spectra in (a), (b) and (d) have been expanded vertically. ![]() A, 1H NMR spectra (400 MHz) for: (a) MeO-PEGN-SuccOH (b) the resveratrol-PEG conjugate mixture from the synthesis of MeO-PEGN-Succ-RSV (c) resveratrol and (d) the solution from (b) after treatment with water and heat (90☌) for ca. ![]()
