Identification and assignment of the absolute configuration of biologically active methyl-branched ketones from limnephilid caddis flies


, : Identification and assignment of the absolute configuration of biologically active methyl-branched ketones from limnephilid caddis flies. European Journal of Organic Chemistry (16): 3175-3179

The glands at the 4th and 5th abdominal sternite of the caddis flies Potamophylax latipennis, P. cingulatus and Glyphotaelius pellucidus contain (S)-4-methyl-3-heptanone (4a), (4S,6S)-4,6-dimethyl-3-octanone (4b), and (4S,6S)-4,6-dimethyl-3-nonanone (4c). As shown by gas chromatography coupled with electrophysiological recordings, these ketones elicit a strong response in the insects' antennae.

We apply damped response theory to the phenomenon of magnetic circular dichroism (MCD), and we investigate how the numerical instability associated with the simulation of the MCD spectrum from individually calculated A and B terms for close lying...
