Properties and reactions

edit

Chavicol is miscible with alcohol, ether, and chloroform. Dimerization of chavicol gives the neo-lignan magnolol.

Uses

edit

Chavicol is used as an odorant in perfumery and as a flavor. It is found in many essential oils, including anise and gardenia.[2]

Biosynthesis

edit

Chavicol is formed in sweet basil (Ocimum Basilicum) by the phenylpropanoid pathway via p-coumaryl alcohol. The allylic alcohol in p-coumaryl alcohol is converted into a leaving group. This then leaves thus forming a cation, this cation can be regarded as a quinone methide which then is reduced by NADPH to form either anol or chavicol.[3]
