  A new simple route for the synthesis of (±)-2-azetidinones starting from β-enaminoketoesters

  摘要：

  beta -Enaminoketoesters 1, obtained through metal-catalysed reaction of methyl acetoacetate with alkyl cyanoformates have been conveniently transformed into beta -aminoesters 4, 5 by reduction of both the carbonyl group and the carbon-carbon double bond of the enaminoester moiety. These intermediates could be easily converted to (+/-)-2-azetidinones 6, 7 structurally related to thienamycin in good yield and high diastereoselectivity. (C) 2001 Elsevier Science Ltd.

  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.
