Chen, Yinbo; Shi, Jinhui; Li, Liang; Liu, Fei; Zhang, Xiquan; Yang, Yulei published an article in 2021. The article was titled 《An alternative synthesis for iloprost via a key bicyclic aldehyde intermediate》, and you may find the article in Tetrahedron Letters.COA of Formula: C8H14O4 The information in the text is summarized as follows:
An alternative synthesis for iloprost has been accomplished in 14 steps via a convergent synthesis starting from com. available (-)-Corey lactone diol. The syntheses employ a new and key chiral bicyclic aldehyde (I) intermediate, which is primed for attachment of the required α-side chain and ω-side chain. In the experimental materials used by the author, we found Diethyl 2-methylmalonate(cas: 609-08-5COA of Formula: C8H14O4)
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.COA of Formula: C8H14O4
