Abstract
Conformationally restricted 2′, 4′-bridged nucleoside analogues are described herein. The compounds can be prepared by cyclization at C2′ and C4′ of nucleosides through a linker or linking molecule. These novel nucleosides have a desired, locked sugar pucker and are potentially useful as pharmaceutical ingredients, and especially for use in treatment of HCV.
