Resumen
Biotransformation is an important tool in organic syntheses, especially for the production of chiral molecules and whenever chemical reactions are inefficient. Fragrance compounds were biotransformed by Trichosporum cutaneum CCT 1903 whole cells. Batch reactions with cis-jasmone (1), (R)-(-)-carvone (3), alpha- and beta-ionones (4, 5) and (R)-(+)-limonene (10) produced 4-hydroxyjasmone (1a), 7,8-epoxyjasmone (1b), 7,8-dihydroxyjasmone (1c), (1S,2R,4R)-neoisodihydrocarveol (3a), (6R)-isoprenyl-(3R)-methyl-2-oxo-oxepanone (3b), (3R)-isopropenyl-6-oxoheptanoic acid (3c), 2,3-epoxy-(5R)-isopropenyl-2-methylcyclohexenoI (3d), alpha-homo-cycloaeraniol (4a), 4-oxo-7,8-dihydro-beta-ionone (5a), uroterpenol (10a) and (R)-(+)-limonene-1,2-diol (10b) as pure samples for spectroscopic identification (H-1 and C-13 NMR,H-1,H-1-gCOSY, HSQC, gHMBC). The stereochemical consequences of the transformations are also discussed. (c) 2006 Elsevier B.V. All rights reserved. 44 2 78 86
