| abstract | (57) [Problem] To provide a method for producing a conjugated triene derivative. SOLUTION: General formula (1) (Wherein, Ar is an aryl group which may have a substituent, The wavy line indicates that either one of the E / Z geometric isomers or a mixture thereof. The general formula (2) in which the disulfone derivative represented by the formula) is reacted with a base And a method for producing a conjugated triene derivative represented by the following formula: And a general formula (5) (Wherein X is a halogen atom, R and wavy lines have the same meanings as described above), and are reacted with an allyl halide derivative in the presence of a basic compound to obtain a sulfone derivative represented by the general formula (3). A method for producing a conjugated triene derivative represented by the general formula (2), wherein the derivative is subjected to a sulfonation reaction to obtain a disulfone derivative represented by the general formula (1), and the derivative is reacted with a base. |
