Application
- Metabolism of ethyl tiglate in apple fruits leads to the formation of small amounts of (R)-ethyl 2-methylbutanoate.: Focuses on the metabolic transformation of ethyl tiglate in apples, which contributes to the fruit′s flavor profile (Hauck et al., 2000).
General description
Ethyl tiglate, an α,β-unsaturated ester, is naturally found in apples. It can be prepared by the esterification of tiglic acid. Ethyl tiglate is a male-specific pheromone found in some Drosophila species that can attract both male and females. Saprochaete suaveolens grown in a culture medium has been reported to produce ethyl tiglate by metabolizing isoleucine.

(S)-Ethyl 2-methylbutanoate is an important aroma compound in apples and serves as an indicator for genuineness of apple products due to its high optical purity of greater than 98% enantiomeric excess [T. Koenig and P. Schreier, Zeitsch. Lebensm.-Unters. Forsch. A

Mature males ofDrosophila borealis andD. littoralis (Diptera: Drosophilidae) produce pheromones that attract both males and females in a wind-tunnel bioassay. Ethyl tiglate is a major pheromone component in both species. Isopropyl tiglate is a minor component, as active as ethyl
