    • Fluorine substituted cyclohexene derivatives are prepared which is useful for intermediates in synthesizing terpene compounds or active components of agricultural agents and medicines, by reacting 4-trifluoromethyl-3-penten-2-one with ethyl acetoacetate. 4-trifluoromethyl-3-penten-2-one which is formed from acetylmethylene triphenylphosphorane and trifluoroacetone is reacted with ethyl acetoacetate in benzene in the presence of sodium ethoxide at 60 deg. C to produce 3,5-dimethyl-5-trifluoromethyl-2-cyclohexen-1-one, which is subsequently reacted with methyl magnesium iodide and ferric chloride to obtain 3,5-dimethyl-5-trifluoromethyl-3-cyclohexen-1-one.

    • PURPOSE: A manufacturing method of chiral α-chlorinated ester derivatives is provided to efficiently manufacture an optical active material with high optical purity by using a chiral catalyst. CONSTITUTION: A manufacturing method of chiral α-chlorinated ester derivatives comprises a step of making a beta-keto ester compound react to 2,3,4,5,6,6-hexachlorocyclohexa-2,4-dienone under the presence of a chiral catalyst. The chiral catalyst is a chiral palladium catalyst. The beta-keto ester compound has a structure represented by chemical formula 3. In chemical formula 3, each of R^1 and R^2 are connected to each other and forms 1-indamone, 2-indanone, 1-tetralone, 5 or 6 rings; and R^3 is a C1-10 alkyl group.
