Keywords: benzoxazole preparation aminophenol beta diketone cyclization; bronsted acid copper iodide catalyzed cyclization benzoxazole preparation.They researched the compound: 2,6-Dimethyl-3,5-heptanedione( cas:18362-64-6 ).Name: 2,6-Dimethyl-3,5-heptanedione. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:18362-64-6) here.
Cyclization reactions of 2-aminophenols with β-diketones catalyzed by a combination of Bronsted acid and CuI are presented. Various 2-substituted benzoxazoles were obtained through these reactions. Different substituents such as Me, chloro, bromo, nitro, and methoxy on 2-aminophenol are tolerated under the optimized reaction conditions.
