ABSTRACT:
Oxidation of 3,7,7-trimethyl-5-oxo-4-oxabicyclo[4.1.0]hept-2-ene with a peroxy acid affords the novel compound 2-acetoxy-6,6-dimethyl-4-oxo-3-oxabicyclo[3.1.0]hexane (IV) via the novel compounds 2,3-epoxy-3,7,7-trimethyl-5-oxo-4-oxabicyclo[4.1.0]heptane (II) and 2-acetyl-6,6-dimethyl-4-oxo-3-oxabicyclo[3.1.0]hexane (III). The four compounds are intermediates to pyrethroid insecticides.
