(1S,3S,7R)-3-Methyl-α-himachalene, the sex pheromone of the male sandfly (Lutzomyia longipalpis) from Jacobina, Brazil, was synthesized enantioselectively by employing Evans’ or Oppolzer’s asymmetric methylation as the key step. The absolute configuration at the ring junction of this pheromone is opposite to that of the known (1R,7R)-α-himachalene of plant origin.
(1 S,3 S,7 R)-3-甲基-α-himachalene,来自巴西雅可比那的雄性fly(Lutzomyia longipalpis)的性信息素,是利用Evans或Oppolzer的不对称甲基化作为关键步骤选择性合成的。该信息素的环连接处的绝对构型与植物来源的已知(1 R,7 R)-α-喜马林烯的构型相反。
