Fig. 10 (a) Head and pro-meso-metanotum of a second instar nymph of Halyomorpha halys, with evident thorns and rectangular apex of the head. (b) Head and pronotum and of fourth instar nymph of Raphigaster nebulosa, with no thorns and triangular-rounded apex of the head. Arrows indicate patterns that differ in the two species.
We describe a novel and straightforward route to all stereoisomers of 1,10-bisaboladien-3-ol and 10,11-epoxy-1-bisabolen-3-ol via the rhodium-catalyzed asymmetric addition of trimethylaluminum to diastereomeric mixtures of cyclohex-2-enones 1 and 2. The detailed stereoisomeric structures of many natural sesquiterpenes with the bisabolane skeleton were previously unknown because of the absence.
