Synthesis of (-)-(6R,10R)-matsuone. Assignment of relative stereochemistry to a pheromone of Matsucoccus pine bast scales
摘要:
A convergent, enantioselective synthesis of (-)-matsuone (1, (2E,4E,6R,10R)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one), the primary sex attractant pheromone of the red pine scale Matsucoccus resinosae, is described.
Synthesis of (-)-(6R,10R)-matsuone. Assignment of relative stereochemistry to a pheromone of Matsucoccus pine bast scales
摘要:
A convergent, enantioselective synthesis of (-)-matsuone (1, (2E,4E,6R,10R)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one), the primary sex attractant pheromone of the red pine scale Matsucoccus resinosae, is described.
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.
