  easily alkylated by the reaction of carboxylic acids with [bis(trifluoroacetoxy)iodo]benzene or [bis(trifluoroacetoxy)iodo]pentafluorobenzene via radical decarboxylative pathways. This system was further applied to the reaction with tetrahydrofurylcarboxylic acid, 1-(2,3,5-tri-O-benyl)-D-ribofuranosylacetic acid, and 1-(2,3,5-tri-O-benzyl)-D-ribofuranosylcarboxylic acid for the model synthesis of C-nucleosides

  DOI：10.1246/cl.1991.1691

  日期：1991.10

  Aromatic heterocycles containing nitrogen atoms were easily alkylated with the half esters of oxalic acid, which were prepared from alcohols, in the presence of [bis(trifluoroacetoxy)iodo]benzene via radical decarboxylative pathways. This is the first method for the alkylation of aromatic heterocycles with alcohols via the formation of half esters of oxalic acid.
