Beschreibung

Allgemeine Beschreibung

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

Anwendung

Employed in the preparation of chiral hydroboration reagents.[1][2][3]

(+)-α-Pinene may be used as precursors to prepare primary, secondary and tertiary γ-amino alcohols and 1,3-diamines, which can be used as chiral catalysts for the addition of diethylzinc to aromatic aldehydes, resulting in chiral 1-aryl-1-propanols with high enantioselectivity.[4]
