Synthesis and properties of the enantiomers of the two artificial fragrances lilial and methylundecanal

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.
