HYDROXYCITRONELLOL Usage And Synthesis

Description

Hydroxyeitronellol has an odor reminiscent of rose and grape hyacinth. May be prepared by hydrogenation (under pressure in presence of Raney Ni) of 3,7-dimethyl-7-hydroxy-octan-l-al; also in good yields by catalytic hydrogenation (using Raney Ni) of 1.2-epoxy-3,7-dimethyl-octan-7-ol.

Chemical Properties

Hydroxycitronellol has an odor reminiscent of rose and grape hyacinth.

Occurrence

Reported found in high bush blueberry, grapes, skim milk powder and white wine.

Definition

ChEBI: Hydroxycitronellol is an aliphatic alcohol.

Preparation

By hydrogenation (under pressure in presence of Raney Ni) of 3,7-dimethyl-7-hydroxy-octan-1-al; also in good yields by catalytic hydrogenation (using Raney Ni) of 1,2-epoxy-3,7-dimethyl-octan-7-ol.
