    • PROBLEM TO BE SOLVED: To provide a method for simply and efficiently producing optically active erythro-3-cyclohexylserine being an intermediate for a medicine such as an intermediate for a medicine (WOO1/40227) known to be useful as an anti-HIV medicine or its Boc compound.
      SOLUTION: The method for producing an N-acyl-D-erythro-3-substituted serine represented by general formula (2) (R
      1 is a 1-10C alkanoyl group, a benzoyl group, a 1-5C alkanoyl group which is substituted with a halogen atom or a benzoyl group which is substituted with a halogen atom; R
      2 is a phenyl group or a cyclohexyl group) comprises asymmetrically hydrolyzing an N-acyl compound of a DL-erythro-3-substituted serine represented by general formula (1) with L-aminoacylase or a substance obtained by immobilizing the enzyme.
