The racemates and enantiomers of triglycerides 1aee (2,3-ditigloyloxypropyl esters of palmitic, palmitoleic, stearic, oleic, and linoleic acids) of male Drosophila fruit flies were synthesized in three steps from the racemate and enantiomers of 2,3-acetoneglycerol (2) via 1-monoglycerides 4aee derived from the above fatty acids. Appropriate conditions were established for the preparation of enantiomerically pure 1-monoglycerides 4aee, and their enantiomeric purities were determined by NMR analysis of the corresponding bis-(R)-MTPA esters. © 2012 Elsevier Ltd.

Pheromonal triacylglycerols and their analogs, 1A, 1B, 2A, 2B, 3A, 3B, and 3C, of male Drosophila fruit flies were synthesized and analyzed by GC-MS. Their GC retention times were found to be a reliable measure to analyze and identify these triacylglycerols with acetyl, oleoyl and tigloyl groups, although the stereo- and regioisomers of 1 (1A and 1B), 2 (2A and 2B), and 3 (3A, 3B, and 3C) could not be distinguished from each other by MS alone. © 2014 Elsevier Ltd.

Both the crystalline enantiomers of 13-methylheptacosane, the female sex pheromone of Cacopsylla pyricola, were synthesized in gram quantities by starting from the enantiomers of citronellal, 1-bromodecane and 1-bromoundecane in 23-28% overall yield (eight steps). © 2011 Elsevier Ltd.
