Engelbrecht, Gerhardus J. et al. published their research in Heterocycles in 1991 | CAS: 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. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Formula: C10H14O4

Palladium catalyzed reactions of unsaturated carbohydrates. A route to C-glycosides was written by Engelbrecht, Gerhardus J.;Holzapfel, Cedric W.. And the article was included in Heterocycles in 1991.Formula: C10H14O4 This article mentions the following:

Glycosyl carbonates e.g., I, are excellent substrates for palladium catalyzed stereoselective C-glycosidations with active methylene compounds giving the C-glycosides in good yields under mild conditions. Thus, I was treated with NaMeC(CO2Et)2 in the presence of Pd(PPh3)4-PPh3 to give >70% the C-glycoside II. In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Formula: C10H14O4).
