Stereoselective palladium catalyzed cyclization on carbohydrate templates- a route to chiral cyclopentanes and some heterocyclic analogs was written by Engelbrecht, G. J.;Holzapfel, C. W.. And the article was included in Tetrahedron Letters in 1991.Product Details of 17920-23-9 This article mentions the following:
Certain pseudoglycals are shown to be excellent substrates for the palladium catalyzed introduction of unsaturated pendants into the 1-, 2- or 4-positions followed by Pd-mediated cyclization. This methodol. provides a ready entry into homochiral substituted cyclopentanes and their heterocyclic analogs. In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Product Details of 17920-23-9).
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. Polyesters are important plastics, with monomers linked by ester moieties. 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.Product Details of 17920-23-9
