On February 17, 2016, Ortiz-Cervantes, Carmen; Flores-Alamo, Marcos; Garcia, Juventino J. published an article.Recommanded Product: 2-((4-Methoxyphenyl)ethynyl)aniline The title of the article was Synthesis of pyrrolidones and quinolines from the known biomass feedstock levulinic acid and amines. And the article contained the following:
A series of N-(alkyl/aryl/aralkyl)-5-methyl-2-pyrrolidones I [R = t-Bu, c-hex, Bn, etc.] was prepared via ruthenium nanoparticles- catalyzed reductive amination of levulinic acid with various amines using formic acid as the hydrogen source. Ruthenium nanoparticles with a mean diameter of cal 3.8 nm were prepared by thermal decomposition of [Ru3(CO)12] in solvent-free conditions. When these reductive thermal reactions were carried out without the catalyst, the pyrrolidons were obtained with low yield and poor selectivity. The reductive amination reaction between levulinic acid and 2-ethynyl aniline surprisingly produced 2-(2,4-dimethylquinolin-3-yl)acetic acid. Furthermore, synthesis of substituted quinolines II [R1 = H, Et; R2 = H, Me, OMe] was achieved through p-toluenesulfonic acid-promoted condensation of levulinic acid and 2-alkynyl anilines. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Recommanded Product: 2-((4-Methoxyphenyl)ethynyl)aniline
