Efficient chemoenzymatic synthesis of enantiomerically pure β-heterocyclic amino acid derivatives
摘要:
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. (C) 2001 Elsevier Science Ltd. Ail rights reserved.
