The metasternal gland secretion of Phoracantha synonyma contains a diversity of volatile components, one of which, 2-hydroxy-6-methylbenzaldehyde (1), is of widespread occurrence in the genus. Threemajor components and several minor components are macrocyclic lactones, of which the following have been positively identified: decan-9-olide (2), (2)-dec-4-en-9-olide (3) and 11-hydroxytetradec-5-en-13-olide (4). The methyl and ethyl esters of 2-methylbutyric and related acids are also present and are responsible for the characteristic odour of the fresh secretion.
Wax esters from fatty alcohols and uncommon fatty acids were synthesized in yields up to 90% when commercially available microbial lipases from
