Provided are methods including a method for industrially producing (2S,12Z)-2-acetoxy-12-heptadecene, which is, for example, a sex pheromone of pistachio twig borer. The methods can include a production method comprising a step of reacting racemic (2RS,12Z)-2-hydroxy-12-heptadecene with vinyl benzoate in the presence of a lipase to obtain a mixture of optically active (2R,12Z)-2-benzoyloxy-12-heptadecene of Formula (R,Z-2) and optically active (2S,12Z)-2-hydroxy-12-heptadecene of Formula (S,Z-1), a step of heating the mixture to distill out the optically active (2S,12Z)-2-hydroxy-12-heptadecene (S,Z-1), and a step of acetylating the optically active (2S,12Z)-2-hydroxy-12-heptadecene (S,Z-1) to obtain optically active (2S,12Z)-2-acetoxy-12-heptadecene of Formula (S,Z-3). ##STR00001##

Disclosed are HPTS series derivatives and a synthesis method thereof, belonging to the field of organic synthesis. The HPTS series derivatives are prepared by introducing alkylamine or alcohol into sulfonic acid groups of HPTS. The synthesis method comprises the following steps: subjecting HPTS and phosphorus oxychloride to heating and reflux reaction for 12 hours under catalysis of DMF to obtain a reaction product; introducing the reaction product into ice water, stirring, precipitating solid, and performing suction filtration to obtain HPTS-SO.sub.2Cl; dissolving the HPTS-SO.sub.2Cl in tetrahydrofuran to prepare solution A, and dissolving alkylamine or alcohol in tetrahydrofuran to prepare solution B; mixing the solution A with the solution B and then reacting for 24 hours at normal temperature, obtaining a product by rotary evaporation, and obtaining a pure compound after separation through columns. The derivatives have strong fat solubility, overcome the defect of a very strong water solubility.
