Pithecellobium dulce

The structures of the di- and trimeric profisetinidins from Pithecellobium dulce (Guamii-chil) were rigorously corroborated via synthesis.The synthetic approach was additionally motivated by the precariousness of unequivocally differentiating between 2,3-cis-3,4-trans-and 2,3-c7.s-3,4-c7.s-confugurations of the chain-extension units on the basis of H NMR coupling constants.Furthermore, the powerful nuclear Overhauser effect (NOE) method for differentiating between 2,4-cis- and 2,4-tra i -substitution is less useful at the di- and trimeric levels due to the adverse effects of dynamic rotational isomerism about the interflavanyl bond(s) on NMR spectra at ambient temperatures. [Pg.576]
