Abstract

S-(+)-4-Methyl-3-heptanone is the principal alarm pheromone of Atta texana. The dextrorotatory form of the ketone has also been identified from Atta cephalotes. Both enantiomers have been synthesized in high optical purity; Atta texana is more responsive to the (+) enantiomer than to the (-) form. These results implicate a chiral receptor system.

摘要

S-(+)-4-甲基-3-庚酮是 Atta texana 的主要报警信息素。这种酮的右旋形式也已从 Atta cephalotes 中鉴定出来。两种对映异构体都以高光学纯度合成；Atta texana 对（+）对映异构体的反应比对（-）对映异构体更敏感。这些结果暗示了一种手性受体系统。
