Method for Direct Synthesis of α-Cyanomethyl-β-dicarbonyl Compounds with Acetonitrile and 1,3-Dicarbonyls was written by Wang, Chenyang;Li, Yabo;Gong, Ming;Wu, Qi;Zhang, Jianye;Kim, Jung Keun;Huang, Mengmeng;Wu, Yangjie. And the article was included in Organic Letters in 2016.COA of Formula: C9H10O3S This article mentions the following:
A novel and efficient method for the synthesis of α-cyanomethyl-β-dicarbonyls in moderate to excellent yields is developed by using inactive CH3CN and simple 1,3-dicarbonyls. A radical mechanism is proposed under the ESI-MS (electrospray ionization mass spectrometry) anal. results of control experiments In the experiment, the researchers used many compounds, for example, Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8COA of Formula: C9H10O3S).
Ethyl 3-oxo-3-(thiophen-2-yl)propanoate (cas: 13669-10-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.COA of Formula: C9H10O3S
