Abstract:
The reaction of methyl a‐diazoacetoacetate with enamines catalyzed by dirhodium and copper complexes underwent formal 1,3‐dipolar addition to give 5‐amino‐4,5‐dihydrofurans in moderate yields. The reaction was suggested to proceed via a nucleophilic addition of enamines to metal‐carbenes and a subsequent intramolecular cyclization of the resulting zwitterionic intermediates.
