An efficient room-temperature visible-light photoredox α-acyloxyalkylation reaction of N-heteroarenes is reported, which relies on the use of ethyl acetate as a cheap and non-conventional radical source. The direct C(sp2)-C(sp3) coupling was extended to a diverse set of mono-, bi-, and tricyclic of N-heteroaromatics, and the optimized photoredox protocol was successfully performed on a multigram scale. The scope of the alkylating agent was also explored and a plausible mechanism was proposed, involving photoinduced single-electron transfer and hydrogen-atom transfer processes.

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