| titleOfInvention | Method for producing (2r)-2-fluoro-2-c-methyl-d-ribono-y-lactone precursor |
| abstract | In the presence invention, a (2R)-2-fluoro-2-C-methyl-D-ribono-[gamma]-lactone precursor is produced in the form of a ring-opened fluorinated compound by reaction of a 1,2-diol with sulfuryl fluoride (SO2F2) in the presence of an organic base and, optionally, a fluoride ion source. The production method of the present invention secures less number of process steps as compared to the conventional production method (shortening of three steps: cyclic sulfurous esterification, oxidation and ring-opening fluorination to one step) and satisfies the requirements for industrial production (high yield and high reproductivity). The thus-obtained (2R)-2-fluoro-2-C-methyl-D-ribono-[gamma]-lactone precursor is useful as an important intermediate for the synthesis of 2'-deoxy-2'-fluoro-2'-C-methylcytidine with antivirus activity. |
