A method for producing an optically active chroman-carboxylate, which comprises esterifying one antipode of a racemic chroman-carboxylic acid in the presence of a biocatalyst in a solvent containing an alcohol, separating the unreacted other antipode of the racemic chroman-carboxylic acid to prepare the objective optically active ester. The above method can be employed for producing an optically active chroman-carboxylate being useful as a raw material for a medicine, an agricultural chemical or the like, in a process which is efficient and can be commercially practiced. |
