Rhodococcus erythropolis AJ270, an amidase-containing microbial whole cell catalyst, enables a highly efficient and enantioselective hydrolytic desymmetrization of a number of prochiral α-substituted α-aminomalonamides in neutral phosphate buffer at 30°C to afford functionalized α-tetrasubstituted α-amino acids in very good chemical yields and high ee.
