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).

We report an efficient and highly enantioselectivehydroboration of aliphatic 1,1-disubstitutedalkenes with pinacolborane using a phosphine-Cu catalyst. The method allows facile preparation of enantiomerically enriched β-chiral alkyl pinacolboronates from a range of 1,1-disubstitutedalkenes with high enantioselectivity up to 99% ee. Unprecedented enantiodiscrimination between the geminal alkyl substituents
