In 2022,Guo, Peng; Yuan, Guo-Cai; Xu, Liu-Hui; Ye, Ke-Yin published an article in Organic Chemistry Frontiers. The title of the article was 《Cobalt-catalyzed modular assembly toward multi-functionalized furan derivatives》.Recommanded Product: Ethyl 3-oxopentanoate The author mentioned the following in the article:
A cobalt-catalyzed modular [3+2] assembling of unsaturated hydrocarbons and β-dicarbonyls was reported. This protocol featured mild reaction conditions and a broad substrate scope, providing facile entries toward diverse multi-functionalized dihydrofurans such as I [R = H, Me, Ph, etc.; R1 = Ph, 2-naphthyl, 2-thienyl, etc.; R2 = Me, Et; R3 = OMe, OEt, Ot-Bu; R4 = H, Ph; R2R3 = (CH2)3] and furans II [Ar = ph, 1-naphthyl, 2-thienyl, etc.; R5 = H, Me, CO2Et, TMS; R6 = OMe, OEt; R7 = Me; R6R7 = (CH2)2, (CH2)3, (CH2)4, CH2CH(Me)CH2, CH2C(Me2)CH2]. The results came from multiple reactions, including the reaction of Ethyl 3-oxopentanoate(cas: 4949-44-4Recommanded Product: Ethyl 3-oxopentanoate)
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.Recommanded Product: Ethyl 3-oxopentanoate
