Visible-Light Photoredox Alkylation of Heteroaromatic Bases Using Ethyl Acetate as Alkylating Agent was written by Gyorfi, Nandor;Kotschy, Andras;Gyuris, Mario. And the article was included in European Journal of Organic Chemistry in 2020.COA of Formula: C11H9NO2 This article mentions the following:

An efficient room-temperature visible-light photoredox α-acyloxyalkylation reaction of N-heteroarenes is reported, which relies on the use of Et 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. In the experiment, the researchers used many compounds, for example, Methyl isoquinoline-3-carboxylate (cas: 27104-73-0COA of Formula: C11H9NO2).

Methyl isoquinoline-3-carboxylate (cas: 27104-73-0) belongs to isoquinoline derivatives. Being an analog of pyridine, isoquinoline is a weak base, with a pKa of 5.14. Lewis acid activation and nucleophilic attack can produce multiple regioisomers in quinolines and pyridines; isoquinolines generally only undergo attack at the 1-position.COA of Formula: C11H9NO2

Decarboxylative C-H functionalization reactions are highly attractive methods for forging carbon-carbon bonds considering their inherent step- and atom-economical features and the pervasiveness of carboxylic acids and C-H bonds. An ideal approach to achieve these dehydrogenative transformations is through hydrogen evolution without using any chem. oxidants. However, effective couplings by decarboxylative carbon-carbon bond formation with proton reduction remain an unsolved challenge. Herein, the authors report an electrophotocatalytic approach that merges organic electrochem. with photocatalysis to achieve the efficient direct decarboxylative C-H alkylation and carbamoylation of heteroaromatic compounds through hydrogen evolution. This electrophotocatalytic method, which combines the high efficiency and selectivity of photocatalysis in promoting decarboxylation with the superiority of electrochem. in effecting proton reduction, enables the efficient coupling of a wide range of heteroaromatic bases with a variety of carboxylic acids and oxamic acids. Advantageously, this method is scalable to decagram amounts, and applicable to the late-stage functionalization of drug mols.
