(+)-α-Longipinene can be used as a starting material for the synthesis of new terpenoids, (+)-(5S)-5,12-dihydroxy-α-longipinene, (-)-(5R)-5,12-dihydroxy-α-longipinene, and (+)-12-hydroxy-α-longipinen-5-one by oxidation reaction using Aspergillus niger as a biocatalyst. It can be oxidized using lead tetraacetate into tertiary alcohol, longi-cis-verbenol, longi-trans-verbenol, longi-cis-β-crysanthenol, longiverbenone, longi-trans- β -crysanthenol, 2 β,3 β -dihydroxylongipinane, 4 α,8-dihydroxy- α -Iongipinene, and 4 β,8-dihydroxy- α -longipinene.
