(+)-Car-3-ene has been converted by a simple route into (-)-cis-caronaldehydic acid hemiacetal, an important intermediate in the commercial production of certain synthetic pyrethroids.

An effective method is suggested for preparation of 4α-hydroxy-6,6-dimethyl-3-oxabicyclo-[3.1.0]hex-2-one, a key intermediate in synthesis of pyrethroids, based on two-step ozonization . The first step included a treatment with ozone of oxidate of (+)-3-carene, and the second one consisted in reductive ozonization of the product of enolization of ketocaronic acid.
Studies toward the Syntheses of Functionally Substituted γ-Butyrolactones and Spiro-γ-butyrolactones and Their Reaction with Strong Acids: A Novel Route to α-Pyrones

A general strategy for the conversion of 5-keto carboxylic acids, 6 (via their enol-lactones 7), to a variety of γ-lactones, 8a-c, and spiro-γ-lactones, 8d-g, is described.Lactones 8b and 8d,e may be further converted into the corresponding α-pyrones, 17b and 17d,e, respectively, in the presence of strong acids.
