Fluorosulfuric acid esters can be produced by reacting alcohols with sulfuryl fluoride (SO

) in the presence of a base and water. As a substrate thereof, optically active secondary alcohols are preferable, and optically active α-hydroxyesters and optically active 4-hydroxyprolines are particularly preferable. By performing the reaction in a two-phase system in the presence of a reaction solvent immiscible with water, a desired reaction proceeds particularly well. The present invention is a production method solving all the problems involved in conventional techniques while being industrially practicable.
氟磺酸酯可以通过醇与磺酰氟(SO2F2)在碱和水的存在下反应而制得。作为其底物,首选光学活性的二级醇,特别是光学活性的α-羟基酯和光学活性的4-羟基脯氨酸。通过在水不溶性反应溶剂的存在下的两相系统中进行反应,所期望的反应进行得特别好。本发明是一种生产方法,在解决传统技术中涉及的所有问题的同时,具有工业上的实用性。
