Domino allylic amination/Sonogashira/heterocyclisation reactions: palladium-catalysed three-component synthesis of pyrroles was written by Lamande-Langle, Sandrine;Abarbri, Mohamed;Thibonnet, Jerome;Duchene, Alain;Parrain, Jean-Luc. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2010.Name: Diethyl 2-(prop-2-yn-1-yl)malonate This article mentions the following:
Three-component reactions with 3,4-diiodoalk-2-enoic derivatives, primary amines, and terminal alkynes proceeded to give trisubstituted pyrroles, e.g., I in fair to good yields in the presence of palladium and copper catalysts under mild reaction conditions. In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Name: Diethyl 2-(prop-2-yn-1-yl)malonate).
Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Name: Diethyl 2-(prop-2-yn-1-yl)malonate
