A fluorine-containing benzaldehyde is reacted with an alkyl Grignard reagent to convert it to a magnesium alkoxide of racemic, fluorine-containing, benzyl alcohol, and subsequently the magnesium alkoxide is reacted with phthalic anhydride to obtain a phthalate half ester of racemic, fluorine-containing, benzyl alcohol, and the half ester is optically resolved by optically active 1-phenylethylamine, and then the ester group is hydrolyzed, thereby producing an optically active, fluorine-containing, benzyl alcohol.
一种含氟苯甲醛和烷基格氏试剂反应,转化为光学异构体的镁烷氧化物,含氟苄醇,随后镁烷氧化物与邻苯二甲酸酐反应,得到光学异构体的含氟苄醇邻苯二甲酸酯半酯,半酯通过光学活性的1-苯乙胺进行光学分辨,然后酯基被水解,从而产生光学活性的含氟苄醇。
