  Synthesis and Characterization of the Four Geometrical Isomers of 3,5-Dodecadienyl Acetate.

  摘要：

  Practical convergent syntheses of the four geometrical isomers of 3,5-dodecadienyl acetate are presented. These substances have been characterized by NMR and mass spectroscopy. (3E,5Z)-3,5-Dodecadienyl acetate is the main female sex pheromone component of the leaf roller Bonagota cranaodes, which is an important insect pest in apples in South America.The isomeric 3,5-dodecadienyl acetates, as pure isomers and in defined mixtures, have been used as trap lures for Eying insects in field screening experiments in Lithuania. Although no insects were found in the control traps, the numbers of males caught in the baited traps were not high enough to be statistically significant.

  nickel-catalyzed enantioselective addition of allylboronic acid pinacol ester [allylB(pin)] to alpha,beta,gamma,delta-unsaturated aldehydes is described. This reaction results in a remarkable inversion of substrate olefin geometry, providing the Z,E-configured reaction product in good enantioselectivity and olefin stereoselectivity. The reaction appears to proceed by conversion of the dienal to an unsaturated

  Tandem Michael addition and Witting or Horner-Wadsworth-Emmons olefination initiated [3+3] annulation between vinyl azides and allylic phosphorus ylides or allylic phosphoryl-stabilized carbanions has been developed. This one-pot protocol furnishes highly functionalized anilines in good to excellent yields under mild, room-temperature conditions. A rational mechanism is also proposed.
