ChemInform Abstract
The key steps in the synthesis of the 4′,1′a-methanocarbocyclic nucleoside (XII) from the title enol (I) are regio- and stereoselective azidoselenylation of the olefin (I) and Simons-Smith cyclopropanation of the olefin (VII). Formation of a 1′,1′a- methanocarbocyclic nucleoside from (I) is previously reported.
