설명

일반 설명

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.

애플리케이션

(−)-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.
