Patent ID: 7358400

Claim:
A method of producing a cyclopropane monoacetal derivative represented by the formula (III) wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 each independently represents a hydrogen atom, a saturated hydrocarbon group optionally having substituent(s), an aryl group optionally having substituent(s), an alkenyl group or an aralkyl group, R 8 represents a saturated hydrocarbon group optionally having substituent(s), an aryl group optionally having substituent(s) or an aralkyl group, and R 9 represents a saturated hydrocarbon group optionally having substituent(s), an aryl group optionally having substituent(s) or an aralkyl group, which comprises reacting a halogenated unsaturated carbonyl compound represented by the formula (II) wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 8 represent as defined above, and X represents a halogen atom, with an alcoholate.
