Description

General description

(+)-α-Pinene, a monoterpene, is a bio-jet fuel precursor. It undergoes ozonolysis to produce secondary organic aerosol (SOA) mass.

Application

(+)-α-Pinene can be used:

• To prepare chiral organoboranes, which are used in the synthesis of optically active compounds and in Suzuki coupling.
• In the synthesis of chiral pyridine-type N-oxides as catalysts for the allylation of aromatic aldehydes.
• To synthesize 2,3-pinane diamine, a chiral auxiliary in several catalysts and reagents.

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