Article Synopsis
  • Researchers synthesized the pheromone component (E,E)-8,10-dodecadienyl acetate and 12 related compounds to create more effective lures for the soybean pod borer pest in China.
  • Various compounds were tested individually and in combinations to see which ones attracted more male pests, with several showing different levels of effectiveness.
  • Certain binary mixtures significantly increased trap catches compared to the standard lure, suggesting these new pheromone blends could be useful for monitoring and controlling L. glycinivorella populations.

AS CORE SKELETONS OF LAMELLARINS: 5,6-Dihydropyrrolo[2,1-a]isoquinolines are one of the important alkaloids that exhibit significant biological activities, in this study, an efficient synthetic route was described for two novel compounds, 5,6-dihydropyrrolo[2,1-a]isoquinolines I and II. Compound I was synthesized from isovanillin with 28.3% overall yield by a six-step reaction while II from 2-(3, 4-dimethoxyphenyl) ethanamine was with 61.

This paper reports two methods of synthesis for 1,2,4-trimethoxy-5-(1-methyl-2-phenyl-vinyl)-benzene, which was a key intermediate to synthesize the various Lamellarins. One method is by using the Wittig-Horner reaction and another is by the Grignard reaction. By conducting contrast experiments, we got the optimal reaction parameters for high yields.
