Heptakis(2,3‐di‐ O ‐methyl‐6‐ O‐tert ‐butyldimethylsilyl)‐β‐cyclodextrin (DIME‐β‐CD) is shown to be an efficient stationary phase of high enantioselectivity towards chiral esters. Different 2‐alkyl‐branched esters have been stereoanalysed using DIME‐β‐CD in enantioselective capillary gas chromatography. The olfactory properties of the enantiomeric pairs are also described.
