## Abstract The absolute configuration of the new bicyclic acetal 2βethylβ1,5βdimethylβ6,8βdioxabicyclo[3.2.1]octane (1), identified as an aggregation pheromone of males of the beech bark beetle, __Taphrorychus bicolor__, was determined by unambiguous synthesis and NMR experiments. The syntheses of
Synthesis of (1S,2R,5R)-2-Ethyl-1,5-dimethyl-6,8-dioxabicyclo(3.2.1) octane, the Aggregation Pheromone of Male Beech Bark Beetles, Taphrorychus bicolor (Col., Scol.). -An enantioselective synthesis of the title compound (V) is described in order to prove the absolute configuration of the natural pr
