The present invention relates to chiral alkoxy alcohols, chiral 1 ,3- phenylene bιs[4-(4-alkoxy)phenylιmιnomethyl]benzoates, and the preparation methods of them In particular, the chiral alkoxy alcohol of the present invention can be used for synthesizing chiral liquid crystal materials, pharmaceuticals, agricultural chemicals, and as intermediates for natural product synthesis Since the chiral compound of 1 ,3-phenylene bιs[4-(4-alkoxy)- phenylιmιnomethyl]benzoate has a lower phase transition temperature and exhibit ferroelectricity or antiferroelectricity depending on the length of chiral (alkoxy)alkyl terminal group, it can be used as an important component in the mixture of smectic liquid crystal
本发明涉及手性烷氧基醇,手性1,3-苯基双[4-(4-烷氧基)苯基亚甲基]苯甲酸酯,以及它们的制备方法。特别是,本发明的手性烷氧基醇可用于合成手性液晶材料、药物、农药,并作为天然产物合成的中间体。由于1,3-苯基双[4-(4-烷氧基)苯基亚甲基]苯甲酸酯的手性化合物具有较低的相变温度,并根据手性(烷氧基)烷基末端基团的长度表现出铁电性或反铁电性,因此它可以作为莎美酸液晶混合物中的重要组分。
