Co(II) catalysed oxidation of α-pinene by molecular oxygen. Part 2
Lajunen, Marja K.,Maunula, Tatja,Koskinen, Ari M.P.
, p. 8167 - 8171 (2000)
This paper reports studies of factors affecting air oxidation of (-)-α-pinene catalysed by Co(II)-pyridine complexes without a concomitant co-oxidant. Observations are presented about the nature and amount of the catalyst, reaction temperature, oxygen flow and solvent vs. non-solvent conditions. In addition, attention has been paid to the influence of added base or acid, and identification of side products. (C) 2000 Elsevier Science Ltd.

2,6-Permethylated β-cyclodextrin-linked iron and manganese porphyrins catalyse the enantioselective oxygenation of racemic mixture of (S)-α-pinene and (R)-α-pinene with molecular oxygen under irradiation with visible light.
Microbial Allyl Rearrangement and Resolution of Acetates of Unsaturated Cyclic Terpene Alcohols by Pseudomonas sp. NOF-5 Strain

Microbial hydrolysis of the acetates of unsaturated cyclic terpene alcohols by Pseudomonas sp.NOF-5 isolated from soil was investigated. (+/-)-trans-Carveyl acetate ((+/-)-trans-3) was enantioselectively hydrolyzed with NOF-5 strain to give (-)-trans-carveol ((-)-trans-2 of 86.6percent optical purity).However, the hydrolysis of (+/-)-cis-3 was less enantioselective, while (+/-)-piperitylacetate ((+/-)-6, a cis and trans mixture) was hydrolyzed to give the (-)-trans- and (-)-cis-piperitols ((-)-trans-5 and (-)-cis-5) in a poor optical yield.In this case, other tert-alcohols, (+)-trans- and (-)-cis-2-p-menthen-1-ols ((+/-)-trans-7 and (-)-cis-7, were also produced.Furthermore, microbial and enzymic allyl rearrangements of (+)-trans-6 and (-)-trans-verbenylacetate ((-)-trans-11) were studied.Biological treatment of (+)-trans-6 and (-)-trans-11 with NOF-5 or its esterase gave (+)-trans- and (-)-cis-7 and (+)-cis-3-pinen-2-ol ((+)-cis-12), respectively.
