In this work, a highly efficient technique has been documented for the one-pot synthesis of pyrano[2,3-d]pyrimidine and pyrido[2,3-d]pyrimidine derivatives. This method employs 2,2’-bipyridine as a cost-effective and proficient organo-catalyst. All reactions take place within reasonable reaction periods, yielding favorable to excellent results. The reusability of the catalyst is also investigated during the reactions. Moreover, a […]
In this research, different alcohols and phenols are subjected to the reaction with HMDS in the presence of ionic liquid and silica-supported catalysts. Silylation was accomplished under mild reaction conditions at room temperature in short reaction times and good to excellent yields.
In this research, we report a novel and green magnetic nanocatalyst; Fe3O4@SiO2@Vitamin C@Fe2O3 for clean synthesis of 3-amino-1-aryl-1H-benzo[f]chromene-2-carbonitriles with high-yield in water as solvent at room temperature. The nanocatalyst is stable under the synthetic conditions and it can be reused several times without considerable reduction in its catalytic activity. The catalyst structure was characterized by […]
