Bagum, Halima’s team published research in Tetrahedron in 2019 | CAS: 609-08-5

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.Reference of Diethyl 2-methylmalonate

Reference of Diethyl 2-methylmalonateIn 2019 ,《Synthetic access to 3,4-disubstituted pyroglutamates from tetramate derivatives from serine, allo-threonine and cysteine》 appeared in Tetrahedron. The author of the article were Bagum, Halima; Christensen, Kirsten E.; Genov, Miroslav; Pretsch, Alexander; Pretsch, Dagmar; Moloney, Mark G.. The article conveys some information:

A route allowing the conversion of substituted tetramates to 3,4-disubstituted pyroglutamates, making use of Suzuki coupling on an enol mesylate, followed by reduction, is both general and fully stereoselective. In the experiment, the researchers used many compounds, for example, Diethyl 2-methylmalonate(cas: 609-08-5Reference of Diethyl 2-methylmalonate)
