Description

  The present invention relates to an optical resolution reagent comprising an optically active binaphthyl compound.

  Since most of the physiologically active substances that control physiological actions in a living body are optically active compounds, separation of compounds that are optical isomers is often performed in the process of synthesis and production. In recent years, optically active compounds have become extremely important in the fields of pharmaceuticals, agricultural chemicals, etc., and efficacy, toxicity, etc. are often different due to differences in absolute configuration, and compounds that are optical isomers must be separated. Was an extremely important task.

  As a method for separating such a compound that is an optical isomer, for example, there is a method using an optical resolution reagent that is an optically active substance that forms a diastereomer by binding to a racemate. In such a method, by reacting a solution containing a racemate (general formula; DL-X) with an appropriate amount of an optical resolution reagent (general formula; LY), (D—X), (L—Y) and ( If two diastereomeric mixtures of (L-X) and (L-Y) are formed, and each can be purified by, for example, chromatography, etc., based on the difference in physical properties such as solubility, optical from each of them. The resolution reagent can be eliminated to obtain compounds (DX and LX) which are target optical isomers (see, for example, Non-Patent Document 1).

  Therefore, the optical resolution reagent is required on the premise that there is a sufficiently large difference in physical properties such as solubility between the two diastereomeric mixtures formed by combining with the racemate of any compound. There has been a demand for a compound that can be used as an optical resolution reagent that is not complicated and can be easily produced.
