of the cucumber beetle. In this context, we developed the asymmetric total synthesis of the aggregation pheromone of A. vittatum, Vittatalactone, to determine its absolute configuration and to further examine the pheromone response in field studies. The synthesis features an enzyme-catalyzed approach toward the deoxypropionate structural motif. A preformed organocopper reagent could then be coupled in

The first asymmetric total synthesis of vittatalactone features the divergent synthesis of two diastereomers to assign the absoluteconfiguration of the natural product. Its consecutive propionate and deoxypropionate stereogenic centers are established by enantioselective o-DPPB directed allylic substitution.
The present invention relates to the chemical synthesis of vittatalactone, the aggregation pheromone of the striped cucumber beetle,
Acalymma vittatum.
