## Abstract A new approach to optically active β‐alkyl‐α‐methylene‐δ‐butyrolactone derivatives was reported from the __Rhodococcus__ sp. AJ270‐catalyzed hydrolysis of appropriate nitriles. The inversion of enantioselectivity of the amidase has been observed when a methyl protection was introduced i
