    • A process for producing a 2-oxobicyclonull3.1.0nullhex-3-ene-6-carboxylic acid derivative represented by a formula: 1 (wherein R1 represents a hydrogen atom, a C1-6 alkyl group, a C3-6 cycloalkyl group, a C3-6 cycloalkyl C1-6 alkyl group, a C1-6 alkyl group substituted with a substituted or unsubstituted phenyl group, a C1-6 alkoxy C1-6 alkyl group, a C1-6 hydroxyalkyl group, a C1-6 alkylthio C1-6 alkyl group, a C1-6 mercaptoalkyl group, or a substituted or unsubstituted phenyl group) characterized by reacting a 4-hydroxy-2-oxobicyclonull3.1.0nullhexane-6-carboxylic acid derivative represented by a formula: 2 (wherein R1 has the same meaning as described above, and R2 represents a hydrogen atom or a protective group of a hydroxyl group) in the presence of an acid or a base. A process for producing the compounds which are useful for efficient syntheses of 2-amino-3-fluorobicyclonull3.1.0nullhexane-2,6-dicarboxylic acids is provided.
    • 一种制备由下式表示的2-氧代双环[3.1.0]己-3-烯-6-羧酸衍生物的方法:其中R 1表示氢原子,C1-6烷基,C3- 6环烷基,C3-6环烷基C1-6烷基,被取代或未取代的苯基取代的C1-6烷基,C1-6烷氧基C1-6烷基,C1-6羟基烷基,C1 -6烷硫基C 1-6烷基,C 1-6巯基烷基或取代或未取代的苯基),其特征在于使由4-羟基-2-氧代双环[3.1.0]己烷-6-羧酸衍生物 式(式中,R 1具有与上述相同的含义,R 2表示氢原子或羟基的保护基)在酸或碱的存在下进行。 提供了可用于高效合成2-氨基-3-氟双环[3.1.0]己烷-2,6-二羧酸的化合物的方法。
