title: Regioselective oxidation of (+)-alpha-longipinene by Aspergillus niger.
abstract: The regioselective oxidation of (+)-alpha-longipinene (1) with sesquiterpen hydrocarbon was investigated using Aspergillus niger (NBRC 4414) as a biocatalyst. Compound 1 was converted to three new terpenoids, (+)-(5S)-5,12-dihydroxy-alpha-longipinene, (-)-(5R)-5,12-dihydroxy-alpha-longipinene, and (+)-12-hydroxy-alpha-longipinen-5-one. These structures were determined by NMR, IR, specific rotation and mass spectral studies.
