METHODS OF PRODUCING 2'-FLUORO-2'-ALKYL-SUBSTITUTED OR OTHER SUBSTITUTED RIBOFURANOSYL PYRIMIDINES AND PURINES AND DERIVATIVES THEREOF

摘要

FIELD: chemistry. ^ SUBSTANCE: present invention relates to methods of producing derivatives of 2'-deoxy, 2'-fluoro-2'-methyl-D-ribonolactone from starting compounds or . ^ EFFECT: obtained derivatives of 2'-deoxy, 2'-fluoro-2'-methyl-D-ribonolactone can be used to produce nucleosides containing 2'-deoxy-2'-fluoro-2'-C-methyl--D-ribofuranosyl nucleosides and having strong anti-HCV activity. ^ 8 cl, 22 ex
