Enzymatic synthesis of (2E,4E)-(6R,10R)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one, the sex pheromone of Matsucoccus matsumurae Japanese pine bast scale
摘要:
The sex pheromone of Matsucoccus matsumurae Japanese pine bast scale (2E,4E)-(6R,10R)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one (1) was synthesized with stereocontrol from (2R,4S)-5-acetoxy 2,4-dimethyl-pentanol (3), which in turn was prepared by lipase-catalyzed transesterification of meso-2,4-dimethyl-1,5-propanediol (2).

The present invention relates to the chemical synthesis of vittatalactone, the aggregation pheromone of the striped cucumber beetle,
Acalymma vittatum.
matsuone (1), female sexpheromone of Matsucoccus resinosae pine scales, were convergently synthesized in high optical purities. The absoluteconfiguration of the natural product has been assigned as (2E, 4E, 6R, 10R)-4,6,10,12-tetramethyltridecan-2,4-dien-7-one. Bioassays with M. resinosae using these stereoisomers reveal that the unnatural (6R, 10S)-isomer mimics the natural pheromone.
