The invention belongs to the field of asymmetrically preparing chiral medicine intermediates in a biocatalysis method, and particularly relates to a method for preparing 3R, 5S-dyhydroxy-6-benzyloxy-ethyl hexanoate with single optical purity via reduction by taking 3, 5- dicarbonyl-6-benzyloxy-ethyl hexanoate as a substrate and taking double carbonyl reductase as a biocatalyst. The method comprises the following steps: (1) adding the substrate, the double carbonyl reductase and a coenzyme cyclic regeneration system mediated by formate dehydrogenase in a reaction liquid, and oscillating for reaction for at least 1 hour, wherein the reaction liquid is the mixed solution of an organic solvent and a buffer solution; and (2) separating and purifying the product obtained in step (1) to obtain a single optical isomer 3R, 5S- dihydroxyl compound. The invention adopts the double carbonyl reductase and is simultaneously combined with the nonaqueous phase solvent system and the coenzyme regeneration system to synthesize the 3R, 5S-dyhydroxy-6-benzyloxy-ethyl hexanoate via catalysis, the optical purity ee and de values are both larger than 99.5%, the concentration of the substrate reaches 150g/L, and the method has wide practical value.
