Conformational equilibria in selected A-type trimeric procyanidinsElectronic supplementary information (ESI) available: The 1H NMR spectra of 1-4 in four different solvents (MeOD, DMSO, (CD3)2OD and pyridine-d5) together with the signal assignments and Table 1SI with energies obtained for the lowest energy conformers of 1-4 are gathered in the ESI. In addition, a detailed description on the ΔG calculations from the temperature NMR spectra is included. See DOI: 10.1039/c4ob02086c
A-type procyanidin trimers cinnamtannin B-1, cinnamtannin D-1, lindetannin, and aesculitannin B were studied in terms of their conformation and interaction with four solvents: methanol, acetone, DMSO and pyridine. The experiments demonstrated that for each trimer there are two principal conformers o...
