A novel synthetic route to chrysanthemic acid, 2-cyclopentylidenmethyl-3,3-dimethylcyclopropanecarboxylic acid, fluorenespiro-2,2-dimethylcyclopropanecarboxylic acid and indenespiro-2,2-dimethylcyclopropanecarboxylic acid, all of them present in pyrethroids of known insecticidal activity, is described. The key step in the synthesis is the aza-di-n-rnethane rearrangement of some 1-aza-1,4,6-trienes

There is provided a novel cyclopropanecarboxyate of the formula (1): wherein R1 represents a hydrogen atom, a fluorine atom, a C1-C4 alkyl group, a C2-C4 alkenyl group, a C2-C4 alkynyl group, a C1-C4 alkoxy group, a (C1-C4 alkyl)oxymethyl group or a (C1-C4 alkyl)thiomethyl group. The cyclopropanecarboxyate has excellent pest control effect.
