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.

Recent metabolic engineering efforts have generated microorganisms that can produce biofuels, including bio-jet fuels, however these fuels are often toxic to cells, limiting production yields. There are natural examples of microorganisms that have evolved mechanisms for tolerating hydrocarbon-rich environments, such
