Ethyl 3-oxopentanoate(cas: 4949-44-4) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Computed Properties of C7H12O3

《Eosin Y-catalyzed one-pot synthesis of spiro[4H-pyran-oxindole] under visible light irradiation》 was written by Chen, Meng-Nan; Di, Jia-Qi; Li, Jiao-Mian; Mo, Li-Ping; Zhang, Zhan-Hui. Computed Properties of C7H12O3 And the article was included in Tetrahedron in 2020. The article conveys some information:

An efficient and simple synthetic approach was developed for the preparation of biol. interesting spiro[oxindole-3,4′-(4’H-pyran)] derivatives via visible light-mediated one-pot, three-component reaction of isatins, 1,3-dicarbonyl compounds and malononitrile by using an inexpensive organic dye, Na2 eosin Y, as the photocatalyst in aqueous Et lactate at ambient temperature The substrate scope of this three-component reaction was expanded to linear 1,3-dicarbonyl compounds as viable starting materials. In the experiment, the researchers used Ethyl 3-oxopentanoate(cas: 4949-44-4Computed Properties of C7H12O3)
