Applied and environmental microbiology, 64(10), 3878-3881 (1998-10-06)
A total of 215 Streptomyces strains were screened for their capacity to regio- and stereoselectively hydroxylate beta- and/or alpha-ionone to the respective 3-hydroxy derivatives. With beta-ionone as the substrate, 15 strains showed little conversion to 4-hydroxy- and none showed conversion

To study the influence of the steric bulk of the substituents at C(5) on the olfactory characteristics of alpha-ionone, the (S)-antipodes of compounds 8-10 were synthesized starting from (S)-alpha-cyclogeraniol (14a). The latter was available in useful preparative yield with 95%

The gas chromatographic enantiomer separation of alpha-ionone was studied with three different chiral stationary phases using as chiral selectors: (1) heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin, dissolved in polysiloxane PS-086, (2) octakis(2,6-di-O-pentyl-3-O-trifluoroacetyl)-gamma-cyclodextrin and (3) octakis(2,6-di-O-pentyl-3-O-butanoyl)-gamma-cyclodextrin, both dissolved in polysiloxane SE-54. The influence of the concentration
