Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8) 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. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.HPLC of Formula: 13669-10-8

Lewis Acid Regulated Divergent Catalytic Reaction between Quinone Imine Ketals (QIKs) and 1,3-Dicarbonyl Compounds: Switchable Access to Multiple Products Including 2-Aryl-1,3-Dicarbonyl Compounds, Indoles, and Benzofurans was written by Chen, Xingyu;Lu, Sixian;Deng, Ping;Chang, Xiaoqiang;Zhao, Yifan;Ma, Yue;Zhang, Dong;Xia, Fei;Yang, Lan;Wang, Jigang;Sun, Peng.

A catalytic Lewis acid regulated reaction between quinone imine ketals (QIKs) and 1,3-dicarbonyl compounds provided a divergent and tunable approach to a variety of skeletons, including a series of 2-aryl-1,3-dicarbonyl compounds, indoles and benzofurans. The use of lithium chloride and ferrous bromide gave C3- or C2-alkylation products of the QIKs. The combination of ferrous bromide and trifluoromethanesulfonic acid delivered indole derivatives Sequential hydrolysis and C3-alkylation occurred in the presence of ytterbium(III) trifluoromethanesulfonate and stoichiometric amounts of water. When the reaction was performed with trifluoromethanesulfonic acid and stoichiometric amounts of water, benzofurans are obtained. This protocol utilizes mild conditions, exhibits regio- and chemoselectivity and has broad functional group tolerance. In the experiment, the researchers used many compounds, for example, Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8HPLC of Formula: 13669-10-8).
