Synthesis of the enantiomers and N-protected derivatives of 3-amino-3-(4-cyanophenyl)propanoic acid
摘要:
Racemic ethyl 3-amino-3-(4-cyanophenyl)propanoate was synthesized and the enantiomers separated through enantioselective N-acylation by Candida antarctica lipase A (CAL-A) in neat butyl butanoate. The free amino acid enantiomers were transformed to the Boc and Fmoc-protected derivatives. (C) 2004 Elsevier Ltd. All rights reserved.
