Caffeyl alcohol is the organic compound with the formula (HO)2C6H3-4-CHCHCH2OH. This colourless solid is related to catechol by attachment to allyl alcohol. It is the precursor to one of the three principal lignols.

Preparation and occurrence[]

In the laboratory, caffeyl alcohol can be synthesized from 3,4-dihydroxybenzaldehyde.[1] It is an intermediate in the biosynthesis of coniferyl alcohol, the conversion being effected by caffeate O-methyltransferase.[2]

Related compounds[]

Two related compounds are caffeyl aldehyde and caffeic acid, the latter also being a minor component of coffee.[3]
