چکیده مقاله
One of the progressive strategies which have recently attracted considerable attention is the usage of ultrasound conditions with heterogeneous catalysts. 2-Amino-4H chromenes are an important class for further development in medicinal and organic synthesis studies due to their potency and a wide spectrum of biological activities including cancer therapy, antiviral, antitumor and sex hormone. The preparation of 2-Amino-4H-Chromenes has been reported using various conditions and catalysts. Most of the reported methods require long reaction times, the use of toxic solvents, low yields, non-reusable catalysts, and stoichiometric reagents. Te synthesis of substances under ultrasonic condition not only requires fewer catalysts and solvents, but also meets the environmental requirements more powerfully [1-2]. In this study, N-doped graphene quantum dots/CoFe2O4 was applied as a magnetically and robust catalyst to prepared the bicyclic 2 amino 4H chromenes (Scheme 1) [3].
