  • Process for producing optically active 2-hydroxy-4-arylbutyric acid or its ester

    公开(公告)日:2001-07-10
    Provided is an industrially useful process for producing an optically active 2-hydroxy-4-arylbutyric acid or its ester. An optically active acyloxysuccinic anhydride is reacted with an aromatic compound in the presence of a Lewis acid to produce an optically active 2-acyloxy-4-oxo-4-arylbutyric acid. The 2-acyloxy-4-oxo-4-arylbutyric acid is converted to an optically active 2-acyloxy-4-arylbutyric acid through catalytic reduction. The 2-acyloxy-4-arylbutyric acid is hydrolyzed in the presence of an acid or an alkali to produce an optically active 2-hydroxy-4-arylbutyric acid. The 2-hydroxy-4-arylbutyric acid is reacted with an alcohol in the presence of an acid to produce an optically active 2-hydroxy-4-arylbutyric acid ester.
    提供了一种工业上有用的生产光学活性2-羟基-4-芳基丁酸或其酯的过程。在路易斯酸的存在下,将光学活性酰氧琥珀酸酐与芳香化合物反应,以产生光学活性2-酰氧基-4-氧代-4-芳基丁酸。通过催化还原将2-酰氧基-4-氧代-4-芳基丁酸转化为光学活性2-酰氧基-4-芳基丁酸。在酸或碱的存在下,将2-酰氧基-4-芳基丁酸解,以产生光学活性2-羟基-4-芳基丁酸。在酸的存在下,将2-羟基-4-芳基丁酸与醇反应,以产生光学活性2-羟基-4-芳基丁酸酯。

    Optically active acyloxysuccinic anhydride is reacted with an aromatic compound in the presence of a Lewis acid to produce an optically active 2-acyloxy-4-oxo-4-arylbutyric acid, which can then be converted into an optically active 2-acyloxy-4-arylbutyric acid by catalytic reduction, and the latter compound hydrolyzed in the presence of an acid or an alkali to produce an optically active 2-hydroxy-4-arylbutyric acid, which can optionally be reacted with an alcohol in the presence of an acid to produce an optically active 2-hydroxy-4-arylbutyric acid ester.
    具有光学活性的酰氧基丁二酸酐路易斯酸存在下与芳香族化合物反应,生成具有光学活性的 2-乙酰氧基-4-氧代-4-芳基丁酸,然后可通过催化还原转化为具有光学活性的 2-乙酰氧基-4-芳基丁酸、后一种化合物在有酸或碱存在的情况下解,生成光学活性 2-羟基-4-芳基丁酸,后者可选择在有酸存在的情况下与醇反应,生成光学活性 2-羟基-4-芳基丁酸酯。
