Efficient chemoenzymatic synthesis of enantiomerically pure β-heterocyclic amino acid derivatives
Enantiomerically pure (S)-pyrazolylalanine and its derivatives are nonproteinogenic amino acids with antidiabetic activity. A short and effective enantioselective synthesis of these compounds is described, using a kinetic resolution by an acylase from Aspergillus sp.
