Stereoisomeric flavor compounds, part LXI: Enantioselective analysis of aroma-relevant dihydrofuranones

The odor impression of the pure enantiomers of various chiral dihydrofuranones which are important flavor compounds has been evaluated by sniffing the well separated optical antipodes in the GC eluate from heptakis(2,3-di-O-methyl-6-TBDMS)-β-cyclodextrin as the chiral phase for capillary gas chromato-graphic separation. Liquid chromatographic separation has been achieved by the use of bonded β-cyclodextrin as the chiral stationary phase and methanol–water as eluent. Enantiomer separation in the latter was improved by addition of triethylammonium acetate to the eluent.
