    摘要: The present invention provides methods for producing a highly pure aromatic bromocarboxylic acid derivative and an aromatic acylthiocarboxylic acid derivative in high yields. The methods of the present invention include reacting an aromatic amino acid in an aqueous solvent in the presence of sodium nitrite, hydrogen bromide and at least one member selected from the group consisting of an aliphatic carboxylic acid and an alcohol, to give an aromatic bromocarboxylic acid derivative, and reacting the aromatic bromocarboxylic acid derivative and an organic thio acid in the presence of an amine to give an aromatic acylthiocarboxylic acid derivative.

    摘要: Novel intermediates of nucleoside derivatives, of which the 6-position of the nucleic acid base moiety is substituted with a halogen atom, are produced. Using those novel intermediates, even substrates, of which the 3'-position of the saccharide moiety is deoxylated, can be substituted at the 2'-position at an extremely high yield. Specifically, by subjecting a 3'-deoxy derivative of inosine to 6-halogenation to give a 6-halide of the derivative, and then subjecting it to 2'-deoxylation/substitution with a fluorine atom or the like, followed by further subjecting it to substitution with an amino group, a hydroxyl group or any other intended substituent at the 6-positioned halogen atom, nucleoside derivatives are produced at a high yield.Methods for producing nucleoside derivatives including 9-(2,3-dideoxy-2-fluoro-.beta.-D-threo-pentofuranosyl)adenine (FddA) and their related compounds, in a simplified manner, at a high yield and at low costs, and especially Economical methods for substituting substrates, of which the 3'-position of the saccharide moiety is deoxylated, at the 2'-position to produce those nucleoside derivatives on an industrial scale are also provided.
