[source] A stereoselective three-component reaction: One-pot synthesis of cis -isoquinolonic acids catalyzed by silica sulfuric acid under mild and heterogeneous conditionsJOURNAL OF HETEROCYCLIC CHEMISTRY, Issue 1 2006Javad Azizian A mild and stereoselective three-component one-step synthesis of cis -isoquinolonic acid using silica sulfuric acid as a heterogeneous catalyst from an aldehyde, amine and homophthalic anhydride in acetonitrile is described. This new method produces pure products in high yields (81-91%). [source] An Efficient Solid Acid Promoted Synthesis of Quinoxaline Derivatives at Room TemperatureCHINESE JOURNAL OF CHEMISTRY, Issue 6 2007Shaabani Ahmad Abstract Quinoxaline derivatives have been synthesized in a very short time with excellent yields by the condensation of 1,2-diamines with aliphatic or aromatic 1,2-dicarbonyl compounds or benzilmonoxime in the presence of silica sulfuric acid as a very inexpensive solid acid catalyst at room temperature. The recovery and reuse of the catalyst are also satisfactory. [source] | ||||||||||
