A method for preparing pregabalin chiral intermediate (R)-3-(carbamoylmethyl)-5-methylhexanoic acid by a biological enzyme method. In particular, the method comprises: reacting compound (I) 3-isobutylglutaric acid, as a raw material, with a nitrogen-containing agent to produce compound (II) 3-isobutylglutarimide; and performing stereoselective ring-opening of compound (II) under the action of a biological enzyme to produce compound (III) (R)-3-(carbamoylmethyl)-5-methylhexanoic acid:
