  • 2-methyl-5(S)-hexanolide(1); the major component of pheromonal blend of the male carpenter bee was synthesized via Homer-Emmons reaction from Ethyl(S)-3-hydroxybutyrate(2a) which had been obtained by Baker's Yeast reduction in overall yield 39%.

  • The seasonal occurrence of smaller clearwing moth (Synanthedon tenuis) was monitored with sex pheromone traps in sweet persimmon orchards in Gimhae and Jinju in 1998, 2001, and 2002. Results indicated that it occurred in two generations a year. The first generation of the moth occurred from mid-May to early July, and the second one_from late July to late September, showing the peaks in early June and early to mid-August, respectively.

  • New synthesis and electroanthennogram (EAG) responses of the pheromones of the diamond back moth Plutella xylostella L. are described. Lithium dianion of propargyl alcohol was alkylated with 1-bromononane to give 2-dodecyn-1-ol, which was converted to 11-dodecyn-1-ol by acetylene-zipper reaction. Dianion of 11-dodecyn-1-ol was alkylated with 1-bromobutane to provide 11-hexadecyn-1-ol, which was in turn reduced over Pd/BaSO4 to afford (Z)-11-hexadecen-1-ol (3). (Z)-11-Hexadecen-1-ol was oxidized and acetylated to (Z)-11-hexadecen-1-al (1) and (Z)-11-hexadecen-1-yl acetate (2), respectively. The electroantennogram (EAG) responses of the diamond back moth to the pheromone compouds thus synthesized were measured.
