Cariello Silva, Guilherme; de Souza, Gabriela F. P.; Salles, Airton G. Jr published an article in 2022. The article was titled 《Catalytic redox-neutral C-H functionalisation with TEMPO in water to access aminomethyl-substituted pyrroles》, and you may find the article in Organic & Biomolecular Chemistry.Computed Properties of C7H12O3 The information in the text is summarized as follows:
Synthesis of aminomethyl-substituted pyrroles I [R1 = H, 4-Me, 4-Cl, etc.; R2 = H, Me; R3 = R4 = Me, Et] via TEMPO-catalyzed redox-neutral C-H functionalization in water was reported. Starting from cheap and com. chem. feedstocks (ketoesters and anilines), this approach delivered targeted products I in good yields and represented an endeavour to address redox economy in radical transformations. The experimental process involved the reaction of Ethyl 3-oxopentanoate(cas: 4949-44-4Computed Properties of C7H12O3)
Ethyl 3-oxopentanoate(cas: 4949-44-4) belongs to ketone compounds. Ketones are highly reactive, although less so than aldehydes, to which they are closely related. Much of their chemical activity results from the nature of the carbonyl group. Ketones readily undergo a wide variety of chemical reactions.Computed Properties of C7H12O3
