Sjc. Taylor et al., DEVELOPMENT OF THE BIOCATALYTIC RESOLUTION OF 2-AZABICYCLO[2.2.1]HEPT-5-EN-3-ONE AS AN ENTRY TO SINGLE-ENANTIOMER CARBOCYCLIC NUCLEOSIDES, Tetrahedron : asymmetry, 4(6), 1993, pp. 1117-1128
For the resolution of the bicyclic lactam 2-azabicyclo[2.2.1]hept-5-en
-3-one, efficient whole cell biocatalysts have been identified and fro
m these, enzymes (lactamases) have been isolated. While the two enzyme
s obtained act on different enantiomers of the lactam, either can be u
sed in scaleable processes to obtain synthons for carbocyclic nucleosi
des having the natural configuration.
