  • A Concise Asymmetric Synthesis of (2<i>S</i>,3<i>S</i>,7<i>S</i>)-3,7-Dimethylpentadecan-2-yl Acetate and Propionate, the Sex Pheromones of Pine Sawflies

    7S)-3,7-Dimethylpentadecan-2-yl acetate (2) and its propionate analogue (3) are the main sex pheromones of all Neodiprion species and Diprion similes, respectively. Starting from (S)-malic acid and employing a highly chemo-, regio-, and stereoselective tandem ester reduction−epoxide formation−reductive epoxide-opening reaction protocol, an efficient total synthesis of (2S,3S,7S)-2 and -3 is reported

    We describe efficient and flexible enantioselective syntheses of the active enantiomers of the pheromones of pine sawflies, including the species Diprion jingyuanensis, their homologs and, stereoisomers, as well as those identified from the Chinese species Diprion jingyuanensis, i.e., 126. A total of 48 compounds, including acetates 78–101 and propanoates 102–125, have been synthesized. Our general

    日期:2007.10
    The stereoselective synthesis of (2S,3S,7S)-3,7-dimethylpentadec-2-yl acetate (2) and propionate (3) was accomplished by utilizing the cheap and easily available chiron (R)-4-methyl-δ-valerolactone (4). The key steps were chelation-controlled addition of Gilmann reagent to chiral β-alkoxy aldehyde 12 and the Cu(I)-catalyzed coupling of Grignard reagent with bromoester 5 in the presence of NMP.

    日期:1979.1
    All of the four possible stereoisomers of 2,3-erythro-3,7-dimethylpentadecan-2-ol 1 were synthesized by a stereospecific SN2 oxirane cleavage of (2S,3S)-2,3-epoxybutane or its antipode with lithium di[(R)- or (S)-4-methyldodecyl]cuprate. Their acetates or propionates were prepared to test their pheromone activity.
