(1R)-(+)-ALPHA-PINENE Usage And Synthesis

Chemical Properties

(1R)-(+)-ALPHA-PINENE is Clear colourless liquid

Uses

(1R)-(+)-α-Pinene is used in hydroboration reactions and the reduction of ketones.

Uses

(+)-alpha-Pinene is employed in the preparation of chiral hydroboration reagents. It is a bronchodilator in humans. α-Pinene is an anti-inflammatory and used as a broad-spectrum antibiotic.It exhibits activity as an acetylcholinesterase inhibitor, aiding memory. It is a biosynthetic base for CB2 ligands, such as HU-308.

Uses

(+)-α-Pinene has been used in a tolerance testing procedure to detect the genes in Marinobacter aquaeolei, for engineering a pinene tolerant Escherichia coli.

Definition

ChEBI: The (+)-enantiomer of alpha-pinene.

General Description

(+)-α-Pinene is a monoterpenoid compound mainly found in Pinus species.

Flammability and Explosibility

Flammable

Purification Methods

(1R)-(+)-ALPHA-PINENE is isomerised by heat, acids and certain solvents. It should be distilled under reduced pressure under nitrogen and stored in the dark. It has been purified via the nitrosochloride [Waterman et al. Recl Trav Chim, Pays-Bas 48 1191 1929]. For purification of optically active forms see Lynn [J Am Chem Soc 91 361 1919].
