  Determination of the absolute configuration of the male aggregation pheromone, 2-methyl-6-(4′-methylenebicyclo[3.1.0]hexyl)hept-2-en-1-ol, of the stink bug Erysarcoris lewisi (Distant) as 2Z,6R,1′S,5′S by its synthesis

  摘要：

  Lipase-catalyzed asymmetric acetylation of a mixture of (6R,1'S,4'S,5'R)- and (6R,1'R,4'R,5'S)-7'-norsesquisabinen-4'-ol (3) afforded a separable mixture of the recovered former and the acetate of the latter. The recovered alcohol was oxidized to (6R,1'S,5'R)-sesquisabina ketone (2), whose absolute configuration could be assigned by its CD comparison with (1R,5S)-sabina ketone (4). Conversion of (6R,1'S,5'R)-sesquisabina ketone (2) to the bioactive pheromone revealed the stereostructure of the male aggregation pheromone of the stink bug Erysarcoris lewisi (Distant) to be (2Z,6R,1'S,5'S)-2-methyl-6-(4'-methylenebicyclo[3.1.0]hexyl)hept-2-en-1-ol (sesquisabinen-1-ol, 1).

The absolute configuration of ketone 2 was assigned by its CD comparison with (1R,5S)-sabina ketone 4. An alternative synthesis of (2Z,6R,1′S,5′S)-1 was achieved without recourse to enzyme by employing Hodgson’s diastereoselective
