Alkylation of Aromatic Heterocycles with Oxalic Acid Monoalkyl Esters in the Presence of Trivalent Iodine Compounds

Abstract

Abstract 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.
