An Efficient Method for Determining the Relative Configuration of Furofuran Lignans by 1H NMR Spectroscopy
Abstract
An efficient 1H NMR spectroscopic approach for determining the relative configurations of lignans with a 7,9′:7′,9-diepoxy moiety has been established. Using the chemical shift differences of H2-9 and H2-9′ (ΔδH-9 and ΔδH-9′), the configurations of 8-H and 8-OH furofuran lignans can be rapidly and conveniently determined. The rule is applicable for data acquired in DMSO-d6, methanol-d4, or CDCl3. Notably, the rule should be applied carefully...
