چکیده

nano silica sulfuric acid as a solid acid, was described to be an effective catalyst for one-pot three-component reaction of kojic acid, aryl aldehydes and indoles for the preparation of 2-substituted aryl (indolyl) kojic acid derivatives. the catalyst was prepared by combination of chlorosulfonic acid to nano silica gel. the size of nanoparticles were observed with sem.all prepared compounds with melting points, 1h nmr and 13c nmr were characterized. high yields, simple operation, easy-work procedure, mild reaction conditions are some advantages of this protocol. the present method does not involve any hazardous organic solvent. therefore, this procedure could be classified as green chemistry.

Kojic Acid Derivatives

Melanin is one of the most important pigments which exist ubiquitously from microorganisms to plants and animals. It is secreted by melanocyte cells and determines the color of skin and hair in mammalians. It protects the skin from photocarcinogenesis by absorbing UV sunlight and removing reactive oxygen species (ROS) (Gupta, 2006; Kim, 2005; Sapkota, 2011). It is formed by enzymatically cataly...

Urea-hydrogen peroxide/silica phosphoric acid-catalyzed oxidation- condensation Tandem reaction: One-pot synthesis of 2-substituted benzimidazoles from alcohols

An efficient one-pot oxidation/condensation tandem process has been developed for the synthesis of 2-substituted benzimidazole derivatives from benzylic alcohols and 1,2-phenylenediamine with use of urea-hydrogen peroxide/silica phosphoric acid  as a bifunctional catalyst. This method provides a rapid and efficient access to 2-substituted benzimidazoles.
