Pyrethroid-like biological activity of compounds lacking cyclopropane and ester groupings

P E Berteau et al. Science. .

Abstract

The following new insecticidal compounds respond to synergism by piperonyl butoxide and block nerve excitability in the same manner as the insecticide allethrin: 1-(4-allethronyl)-acetyl-2,2-dimethyl-3-isobutenylcyclopropane (the ketone analog of allethrin) and the esters of 5-benzyl-3 furylmethanol with 2,2,3,3-tetramethylcyclopropanecarboxylic acid, 2,2,3,3-tetramethylaziridinecarboxylic acid, and N, N-diisopropylcarbamic acid. Therefore pyrethroid-like activity is not restricted to esters of cyclopropanecarboxylic acids.
