Enantioselective and Regioselective Friedel-Crafts Alkylation of Pyrroles with Nitroalkenes Catalyzed by a Tridentate Schiff Base-Copper Complex was written by Guo, Fengfeng;Chang, Dalu;Lai, Guoyin;Zhu, Tao;Xiong, Shunshun;Wang, Sujing;Wang, Zhiyong. And the article was included in Chemistry – A European Journal in 2011.Recommanded Product: Ethyl 4-methyl-1H-pyrrole-3-carboxylate This article mentions the following:
A mild and highly efficient catalytic system has been developed for the asym. Friedel-Crafts alkylation of pyrroles with nitroalkenes. High yields, and excellent enantioselectivities and regioselectivities were obtained for a broad range of substrates. The synthetic utility of this methodol. and mechanistic studies involving a novel, neg., nonlinear effect are also presented. In the experiment, the researchers used many compounds, for example, Ethyl 4-methyl-1H-pyrrole-3-carboxylate (cas: 2199-49-7Recommanded Product: Ethyl 4-methyl-1H-pyrrole-3-carboxylate).
Ethyl 4-methyl-1H-pyrrole-3-carboxylate (cas: 2199-49-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.Recommanded Product: Ethyl 4-methyl-1H-pyrrole-3-carboxylate
