  Sex Pheromone of the Pine Sawfly, Macrodiprion nemoralis. Stereoselective Synthesis of the Sixteen Stereoisomers of 3,7,9-Trimethyl-2-tridecyl Acetate.

  摘要：

  The sixteen stereoisomers of 3,7,9-trimethyl-2-tridecyl acetate (5Ac) were prepared individually, each in over 99.5% stereochemical purity. The syntheses were based on the ring opening of a pure enantiomer of cis-3,4-dimethyl-gamma-butyrolactone using a pure stereoisomer of 1-lithio-2,4-dimethyloctane, the two stereogenic centres of which were introduced with high selectivity by alkylations of the amide enolates from the appropriate enantiomers of pseudoephedrine. (2S,3R,7R,9S)-3,7,9-Trimethyl-2-tridecyl acetate (SRRS-5Ac) has recently been found to be the major component of the female sex pheromone of Macrodiprion nemoralis (Hymenoptera: Diprionidae). A synthetic method for the preparation of a sixteen isomer mixture of 5Ac is also presented. This mixture has been found to be biologically active in field tests.

  All of the four possible stereoisomers of 5,9-dimethylpentadecane, the major sex pheromone component of the coffee leaf miner moth (Perileucoptera coffeella), were synthesized by using the methyl esters of (S)- and (R)-3-hydroxy-2-methylpropanoic acid as chiral sources for the purpose of determining the stereochemistry of the pheromone.

  The total synthesis of majusculamide D (1) was achieved from commercially available materials. In addition, we synthesized eight analogues including three stereoisomers of majusculamide D that differ in the fatty acid chain. Six analogues including a simplified analogue 29 exhibited significant nanomolar-level IC50 values against Panc-1 cells in MTT assays. A preliminary SAR analysis indicated that
