General description

2-Azabicyclo[2.2.1]hept-5-en-3-one is also referred as vince lactam. It is a versatile intermediate in the synthesis of carbocyclic nucleosides. 2-Azabicyclo[2.2.1]hept-5-en-3-one and its monohydrated complex was investigated in a supersonic jet by Fourier transform microwave spectroscopy.

Application

2-Azabicyclo[2.2.1]hept-5-en-3-one was used in:
  • preparation of (3aS,4R,6R,6aR)-6-((methoxy-methoxy)methyl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-amine, a precursor of analog of bredinin
  • synthesis of therapeutic drugs
  • chemoenzymatic synthesis of (−)-carbovir

The natural nucleoside antibiotic, bredinin, exhibits antiviral and other biological activities. While various nucleosides related to bredinin have been synthesized, its carbocyclic analog has remained unknown. Synthesis of this heretofore unknown analog of bredinin is described.

2-Azabicyclo[2.2.1]hept-5-en-3-one (ABH or Vince lactam) and its monohydrated complex (ABH···H(2)O) have been observed in a supersonic jet by Fourier transform microwave spectroscopy. ABH is broadly used in the synthesis of therapeutic drugs, whereas the ABH···H(2)O system offers a simple model
