Racemic undecan-x-ols (x = 2,3) used as starting materials in a biocatalysed enzymatic acylation with vinyl acetate in the presence of Novozym 435®. As result enantiomerically pure alcohols and their acetates have been obtained. The odours of each of the enantiomers have been compared with those of the racemic mixtures. Enantiomerically pure undecan-2-ols as well as their acetates have intense odours which differ in type, since their intensity is similar, the odour of each racemate comprises the odours of both enantiomers. Racemic undecan-3-ol has the odour of the R enantiomer only, because the opposite enantiomer is almost odourless. The odour of the racemic undec-3-yl acetate is faint with a fatty-soapy note despite of the fact that both enantiomers exhibit pleasant floral odours. (original abstract)
