Abstract

magnified image

The 1,3‐dibromo‐5,5‐dimethylhydantoin (DBH) was found to efficiently catalyze the one‐pot synthesis of highly functionalized tetrasubstituted furan derivatives by the reaction of 1,4‐diarylbut‐2‐ene‐1,4‐diones and acetoacetates in i‐PrOH as the solvent at 80–90° for 3–7 h. The products were formed in high yields (82–95%) under mild and neutral conditions.
