Piceol is a phenolic compound found in the needles and in mycorrhizal roots of Norway spruces (Picea abies).[1][2] Picein is the glucoside of piceol.[3]
Uses
[edit]Piceol is used in the synthesis of several pharmaceutical drugs including octopamine, sotalol, bamethan, and dyclonine.[citation needed]
Piceol can be used to make acetaminophen by condensation with hydroxylamine and subsequent Beckmann rearrangement in acid.[4]
Anticonvulsants are also possible by Mannich reaction:[5]
Metabolism
[edit]Diprenylated derivatives of piceol can be isolated from Ophryosporus macrodon.[6]
4-Hydroxyacetophenone monooxygenase is an enzyme that transforms piceol into O-acetylhydroquinone. This enzyme is found in Pseudomonas fluorescens.
