Reaction Discovery Using Neopentylene-Tethered Coupling Partners: Cycloisomerization/Oxidation of Electron-Deficient Dienynes was written by Kramer, Nicholas J.;Hoang, Tung T.;Dudley, Gregory B.. And the article was included in Organic Letters in 2017.Electric Literature of C10H14O4 This article mentions the following:
A rhodium-catalyzed cycloisomerization and oxidation of tethered dienynes for the synthesis of indans, e.g. I, is described. An auxiliary fragmentation/olefination method (also described herein) provides novel access to tethered alkyne-dienoate substrates. The reported method circumvents current limitations in and expands the scope of inverse-demand Diels-Alder-type cycloadditions Traditional discovery substrates involving malonate-, ether- and sulfonamide-based tethers are problematic in the current methodol., underscoring the unique virtue of neopentylene-tethered substrates for reaction discovery. In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Electric Literature of C10H14O4).
Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Electric Literature of C10H14O4
