Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8) 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.Computed Properties of C9H10O3S

Copper-Mediated Aerobic Synthesis of 3-Azabicyclo[3.1.0]hex-2-enes and 4-Carbonylpyrroles from N-Allyl/Propargyl Enamine Carboxylates was written by Toh, Kah Kah;Wang, Yi-Feng;Ng, Eileen Pei Jian;Chiba, Shunsuke. And the article was included in Journal of the American Chemical Society in 2011.Computed Properties of C9H10O3S This article mentions the following:

Synthetic methods for 3-azabicyclo[3.1.0]hex-2-enes, e.g. I, and 4-carbonylpyrroles, e.g. II, have been developed that use copper-mediated/catalyzed reactions of N-allyl/propargyl enamine carboxylates under an O2 atmosphere and involve intramol. cyclopropanation and carbooxygenation, resp. These methodologies take advantage of orthogonal modes of chem. reactivity of readily available N-allyl/propargyl enamine carboxylates; the complementary pathways can be accessed by slight modification of the reaction conditions. In the experiment, the researchers used many compounds, for example, Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8Computed Properties of C9H10O3S).
