Abstract

The enantiomers of the two artificial fragrances 3-(4-tert-butylphenyl)-2-methylpropanal (lilial) and 2-methylundecanal are synthesized with high enantiomeric purity using the SAMP/RAMP hydrazone method. The enantiomeric excesses are determined by HPLC via the corresponding SASP hydrazones. The olfactorial qualities of the enantiomers are described.
