Structures of the pyrazines from the mandibular gland secretion of the ponerine ant Dinoponera australis
Abstract
Two aldehydes and eleven pyrazines have been identified in the mandibular glands of the ant D. australis. Three of the tetraalkylpyrazines are novel, and a further two have their structures confirmed for the first time. Microgram scale reactions and syntheses were used, together with mass spectrometry, to establish these structures.
