Phenolic 2‐methylbutanoates are known to be characteristic components of various essential oils, but their optical purity is not known. Enantiomeric pseudoisoeugenyl 2‐methylbutanoates have been synthesized and their sensory properties are found to depend on the optical and geometrical isomerism of the components investigated. Furthermore, (S)‐2‐methylbutanoates have been detected as the genuine esters from Pimpinella anisum (L.), Arnica (unknown splecies) and Pimpinella saxifraga (L.), using ester hydrolysis and subsequent enantioselective MDGC analysis of the corresponding 2‐methylbutanoic acid.
