The scope and limitations of the enzymatic resolution of alpha,alpha-disubstituted alpha-amino acid amides by an amino acid amidase from Mycobacterium neoaurum and of the corresponding ethyl esters with Pig liver esterase (PLE) have been studied. Moderate enantiomeric excesses were obtained with PLE, with only a narrow substrate specificity. Mycobacterium neoaurum on the contrary yields a broad range of S-alpha,alpha-disubstituted alpha-amino acids 1 and the corresponding R-amides 2.
