A new simple route for the synthesis of (±)-2-azetidinones starting from β-Enaminoketoesters
摘要:
beta-Enaminoketoesters, obtained by metal-catalyzed reaction between alkyl acetoacetates and alkyl cyanoformates, are useful starting materials for rapid access to beta-acetyl-dehydroaspartic acrid derivatives which could be transformed into (+/-)-2-azetidinones bearing a 1-hydroxy-ethyl substituent through suitable reductive processes.
