  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.
