Abstract

Dibenzoylmethanes (DBMs) belong to a small group of flavonoids, known as beta-hydroxychalcones, rarely found in nature. Despite their biological and chemotaxonomic importance, the absolute configuration of C-8 substituted DBMs has never been reported. Herein, the absolute stereochemistry of 2'-methoxy-8-(alpha-alpha-dimethylallyl)-{[}3',4':4 `',5 `']-furan-dibenzoylmethane is determined using the VCD exciton chirality method, which may be safely applied to other members of this class.
