Owing to the important physiological and pharmacological activities of benzofuran compounds, the exploration for efficient synthesis methods is of great value and wide application. Aurone-derived azadienes have been identified to be effective reactants in the field of organic synthesis owing to the driving force of aromatization. A large number of reactions based on 1,4-conjugate addition and tandem cyclization have been reported, which exhibited great advantages in the construction of heterocycles with benzofuran skeletons. In this paper, the recent progress in the chemical transformations of aurone-derived azadienens is reviewed, with emphasis on the employed catalytic system and the plausible mechanism of some reactions.
Key words: benzofuran derivatives, aurone-derived azadienes, 1,4-conjugate addition, cyclization reactions
