(?)-α-Phellandrene is a colorless
liquid with a citrus odor and a slight peppery note. It is isolated, for example, from
Eucalyptus dives oil. Pinenes are widespread, naturally occurring terpene hydrocarbons. The α- and
β-forms occur in varying ratios in essential oils. | [Uses]
(R)-(-)-α-Phellandrene undergoes [4+2] cycloaddition with 2-naphthyl acetylenecarboxylate to form a chiral diene, which can act as a ligand for the rhodium-catalyzed asymmetric addition reactions. It may be used to synthesize (1S,5R)-5-(1-methylethyl)-2-methylidene-3-cyclohexen-1-yl hydroperoxide, which on reduction forms trans-yabunikkeol. | [Definition]
ChEBI: (-)-alpha-phellandrene is the (R)-(-)-stereoisomer of alpha-phellandrene. It is an enantiomer of a (+)-alpha-phellandrene. | [General Description]
(R)-(-)-α-Phellandrene is a monoterpene derivative. | [Flammability and Explosibility]
Flammable | [Purification Methods]
Purify it by gas chromatography on an Apiezon column. Also purify it by steam distillation (with 0.5% hydroquinone), then re-distil it through a 50 plate bubble cap column b 72-72.5o/22mm [Pines & Eschinazi J Am Chem Soc 77 6318 1955]. UV: max 263nm ( 3,345) in octane. [Read & Storey J Chem Soc 2770 1930, Beilstein 5 III 341, 5 IV 436.] | [Toxics Screening Level]
The screening level is being set at the default of 0.1 μg/m3 with annual averaging. |
