| Application: | (−)-α-Pinene can be used: • To prepare chiral γ-amino alcohols, which are used as catalysts for the preparation of chiral 1-aryl-1-propanols using aromatic aldehydes. • As a substrate in the study of its t-BuOOH mediated oxidation catalyzed by Co(II) complex. • As a starting material for the synthesis of polyfunctionalized cyclobutane derivatives. |
| General description: | α-Pinene is a monoterpene used in industries like fragrance, pharmaceuticals, flavor, and cosmetics. It is a major component of pine oil and turpentine oil. Isomerization of α-pinene yields industrially important compounds like camphene, limonene, and p-cymene. |
