Chemical Properties

(?)-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.

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.]

Check Digit Verification of cas no

The CAS Registry Mumber 4221-98-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4221-98:
(6*4)+(5*2)+(4*2)+(3*1)+(2*9)+(1*8)=71
71 % 10 = 1
So 4221-98-1 is a valid CAS Registry Number.

High-Throughput Synthesis of (S)-α-Phellandrene through Three-Step Sequential Continuous-Flow Reactions

Miller, Samuel J.,Ishitani, Haruro,Furiya, Yuichi,Kobayashi, Shū

supporting information, p. 192 - 198 (2021/02/05)

The combination of continuous-flow processing with heterogeneous catalysts allows for efficient, sustainable, multistep synthesis. Here, we report the continuous-flow synthesis of a valuable terpene product, phellandrene, from a readily available natural feedstock. The protocol consists of selective hydrogenation using a highly active and stable supported platinum catalyst, dehydrative hydrazone formation, followed by the Shapiro reaction. Appropriate design of the reactor allowed for high productivity and space-time yield. Phellandrene was synthesized on a 30-g scale over 6 h, giving high yields, purity, and productivity.

Triphenylpyrylium tetrafluoroborate-sensitized photochemistry of the terpenes sabinene, α-phellandrene, and α- and γ-terpinene

Climent, Maria-Jose,Miranda, Miguel Angel,Roth, Heinz Dieter

, p. 1563 - 1567 (2007/10/03)

The triphenypyrylium tetrafluoroborate (TPT)-sensitized reactions of several terpene donor molecules, including sabinene (1), α-phellandrene (4), α-terpinene (5) and γ-terpinene (6) give rise to significantly different products than reactions induced by other electron-transfer sensitizers, such as 1,4-dicyanobenzene (DCB). The divergent reactions require decidedly different key intermediates; the products obtained with TPT can be explained by dissociative recombination of the intermediate radical-radical cation pair in the triplet state, generating donor-derived biradicals.

Isotopically Sensitive Branching as a Tool for Evaluating Multiple Product Formation by Monoterpene Cyclases

Wagschal, Kurt,Savage, Thomas J.,Croteau, Rodney

, p. 5933 - 5944 (2007/10/02)

The deuterated substrates geranyl pyrophosphate and geranyl pyrophosphate were employed to examine isotopically sensitive branching in the biosynthesis of monoterpene olefin isomers.By this method, (-)-α-pinene and (-)-β-pinene were shown to be synthesized via a common intermediate by a single cyclization enzyme from grand fir (Abies grandis), as were (-)-α-phellandrene and (-)-β-phellandrene by a single cyclase from lodgepole pine (Pinus contorta).Kinetic isotope effects were determined for the various deprotonations leading to the pinenes and phellandrenes.Key Words: Isotopically sensitive branching, monoterpene biosynthesis, monoterpene cyclase, resin biosynthesis, kinetic isotope effect.
