Stereoisomeric Flavour Compounds. Part LVII: The Stereoisomers of 3-Oxo-p-menthane-8-thiol acetate, Simultaneously Stereoanalysed with their Corresponding Thiols

The stereoisomers of 3-oxo-p-menthane-8-thiol acetate have been synthesized by acetylation of optically pure stereoisomers of 8-mercapto-p-menthan-3-one. The stereoisomers were identified by H-1/C-13-NMR spectroscopy and CGC-MS. Their sensory properties are described. Their chirospecific analysis is reported simultaneously with the stereoisomers of their corresponding thiols using selectivity adjusted enantioselective capillary gas chromatography with octakis(2,3-di-O-acetyl-6-O-tert-butyldimethylsilyl)-gamma-cyclodextrin as the chiral stationary phase.
