Zusammenfassung

Die beiden stereoisomeren Nepetalactone wurden durch Gaschromatographie getrennt. Es wurde gezeigt, dass dastrans-cis-Isomere (II) auf Katzen anziehend wirkt. Dascis-trans-Isomere (I), das etwa 75% der Mischung darstellt, ist bedeutend weniger aktiv, möglicherweise völlig inaktiv.

    For nepetalactones distilled from oil of catnip, [α]D23-13.0° (CHCl3) has been reported, and for nepetalactones from the pyrolysis of nepetalic acid, +3.6° (S. M. McElvain, R. D. Bright, andP. R. Johnson, J. Amer. chem. Soc.63, 1558 (1941)). These preparations probably contained small amounts of a strongly levorotatory impurity.Google Scholar
