Iron-catalyzed oxidative cyclization of olefinic 1,3-dicarbonyls with ketone C(sp3)-H bonds through C-C and C-O bond formations has been described for the first time. A broad substrate scope and ease of scale-up are the attractive features of this synthetic method, which provides a series of potentially bioactive 2,3-dihydrofurans. The reaction pathway is proposed to involve a radical addition of the in situ-formed α-carbonyl radical to the C=C bond of olefinic 1,3-dicarbonyls followed by intramol. 5-endo-trig cyclization. The experimental process involved the reaction of Diethyl 2-methylmalonate(cas: 609-08-5Quality Control of Diethyl 2-methylmalonate)
Diethyl 2-methylmalonate(cas: 609-08-5) belongs to aliphatic hydrocarbons. Aliphatic hydrocarbons belong to the most abundant fraction in crude oil. Aliphatics molecules are linear or branched open-chain structures such as n-alkanes, isoalkanes, cycloalkanes (naphthenes), terpenes and steranes.Quality Control of Diethyl 2-methylmalonate
