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.

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).
