5-Substituted 2,2-dimethylcyclohexane-1,3-diones proved to be valuable precursors of (d,l) cis-chrysanthemic acid (3-isobutenyl-2,2-dimethyl-1-cyclopropanecarboxylic acid) and some of its analogues. The esters derived from the two stereoisomeric 2-desmethyl cis-chrysanthemic acids and 3-phenoxybenzaldehyde cyanohydrin [2-hydroxy-2-(3-phenoxyphenyl)acetonitrile] have been tested against three species of insects. The cyclopropyl ester with all three substituents cis to one another was found to be the most active.
