Kwakhurin, a unique isoflavone with rejuvenating activity from "kwao keur": Further characterization by 2D-NMR spectrometry and synthesis of triisopropylkwakhurin

Kwakhurin (5), a characteristic isoflavone component of Pueraria mirifica which has been used in folk medicine as "kwao keur" for rejuvenating purpose, was structurally approached by 2D-NMR experiments. Furthermore, the synthesis of kwakhurin (5) was attempted starting from the methyl ketone (12). Thus, deoxybenzoin derivative (22) was prepared by Friedel-Crafts acylation after protection of the phenolic function with a triisopropyl group. Modification of the substituents, O-prenylation, prenyl 1,3-rearrangement, and O-methylation afforded kwakhurin triisopropyl ether (38).
