Paravespula vulgaris

The pheromone components of the wasp Paravespula vulgaris, (2R, 5S)- and (2S, 5S)-2-methyl-l,6-dioxaspiro[4.5]decane, was synthesized diastereoselectively. ...

Other spiroacetal natural products have been prepared using malic acid-derived epoxides as the chiral source (Scheme 54). Chalcogran (407, R=CH3, = 1) is the principal component of the aggregation pheromone of the beetle Pityogenes chalcographus (L.), a pest of Norway spruce. Spiroacetal 407 (R—H, = 2) is a minor volatile component found in the common wasp, Paravespula vulgaris. 

Main component of the odour of the common wasp, Paravespula vulgaris which appears to act as aggression inhibitor. Ident. by glc/ms.
