Stereoselective Synthesis of 2‘-C-Methyl-cyclopropyl-Fused Carbanucleosides as Potential Anti-HCV Agents

Abstract
Stereoselective synthesis of 2‘-C-methyl-cyclopropyl-fused carbanucleosides was accomplished via stereoselective cyclopropanation, regioselective cleavage of the isopropylidene group, stereoselective Grignard reaction, and cyclic sulfate chemistry.
