And the article contained the following:
Herein, a feasible electrosynthesis method to access 1,4-dicarbonyl compounds such as I [R = Ph, 4-MeC6H4, 2-thienyl, etc.; R1 = Me, OMe, OEt, Oi-Pr; R2 = Me; R3 = Me; R2R3 = (CH2)3, (CH2)4, (CH2)5] had been developed from simple alkynes and 1,3-dicarbonyl compounds When the undivided cell was combined with the constant current mode, aryl alkynes containing numerous medicinal motifs with 1,3-dicarbonyl esters or ketones reacted smoothly. External oxidant and catalyst-free conditions conformed to the requirements of green synthesis. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Reference of Methyl 2-cyclopentanonecarboxylate
