Abstract: Furan derivatives R 0060Efficient One-Pot 1,3-Dibromo-5,5-dimethylhydantoin (DBH)-Catalyzed Synthesis of Highly Substituted Furans. -An advantage is the better yield of products compared with previously reported methods. In addition, the catalyst is inexpensive and not moisture-sensitive. -(GHASEMNEJAD-BOSRA, H.; FARAJE, M.; HABIBZADEH, S.; Helv. Chim. Acta 92 (2009) 3, 575-578; Dep. Chem., Sch.

New and convenient one-pot syntheses of 2-substituted aryl (indolyl) kojyl thioether from 2-substituted aryl (indolyl) kojic acids have been found. Firstly, the 2-substituted aryl (indolyl) kojic acids were readily obtained from coupling of aldehyde, kojic acid and indoles in the presence of p-toluenesulfonic acid as catalyst in good yields and with high selectivity. Then, 2-substituted aryl (indolyl) kojic acids were reacted with thionyl chloride to afford corresponding 2substituted aryl (indolyl) kojic chlorides. Finally, the 2-substituted aryl (indolyl) kojic chloride derivatives were reacted with benzenethiols in presence of triethylamine in t etrahydrofurane to afford the corresponding thioether derivatives in good yields. Keywords : The one-pot synthesis, 2-substituted aryl (indolyl) kojic acids, 2-substituted aryl (indoly l) kojic ch lorides, ptoluenesulfonic acid, ko jyl thioether.
