A concise approach for determining the relative configuration of H-7 and H-8 in 8,4′-oxyneolignans by ¹H NMR spectroscopy

Abstract

The chemical shift difference between H-9a and H-9b can be used to accurately and rapidly determine the relative configuration of H-7 and H-8 in three types of 8,4′-oxyneolignan glucosides.
