Dihydrokawain Structural

What is Dihydrokawain?

Chemical properties

White-pale yellow powder, soluble in methanol, ethanol, DMSO and other organic solvents, derived from the rhizome of kava-kava (Piper methysticum G. Forst).

The Uses of Dihydrokawain

(+)-(S)-Dihydrokavain is a kavalactone found in kava beverages consumed by South Pacific islanders. Furthermore, roots and extracts of the kava plant have been used in herbal medicine to treat sleep disturbances, as well as stress and anxiety.

What are the applications of Application

7,8-Dihydrokawain is a compound that displays neuroprotective and antinociceptive activity

Definition

ChEBI: Dihydrokavain is a member of 2-pyranones and an aromatic ether.

What are the applications of Application

Dihydrokavain is one of the six major kavalactones found in the kava plant; appears to contribute significantly to the anxiolytic effects of kava, based on a study in chicks.Used in herbal medicine to treat sleep disturbances, as well as stress and anxiety.

Preparation

Starting from 2,3-O-isopropylidene-D-glyceraldehyde (2) as chiral material, the naturally occurring (S)-(+)-dihydrokavain (1a) was synthesized by a procedure that involves a sonochemical Blaise reaction as the key step. The absolute configuration of (S)-(+)-dihydrokavain (1a) is demonstrated for the first time by total synthesis from a chiral source. Its opposite enantiomer, (R)-(–)-dihydrokavain (1b), was also synthesized after inversion of the chiral center in a Mitsunobu reaction.
