PROCESS FOR THE PREPARATION OF (+-)- R-7- BENZYLOXYMETHYL- CYCLOPENTA- CIS- 4, 51, 3- OXAZOLO3, 2-A PYRIMIDINONE COMPOUNDS AS VERSATILE PRECURSORS OF CARBOCYCLIC NUCLEOSIDES.

摘要

The present invention describes a novel method for the synthesis of carbocyclic nucleosides by means of the direct coupling of a nitrogenous base to carbocyclic rings through the reaction of iodinefunctionalization of olefins.
