tailieunhanh - A novel one-pot and rapid synthesis of polyfunctionalized benzo[a]pyrimido[5’,4’:5,6] pyrido[2,3-c]phenazine derivatives under microwave irradiation

A one-pot, environmentally friendly, and efficient protocol for the synthesis of novel polyfunctionalized benzo[a]pyrimido[5’,4’:5,6]pyrido[2,3-c ]phenazine derivatives has been reported by a one-pot, four-component sequential reaction between 2-hydroxynaphthalene-1,4-dione, benzene-1,2-diamines, benzaldehydes, and 6-amino-1,3-dimethyluracil in the presence of p-TSA as a nontoxic, inexpensive, ecofriendly, and efficacious solid acid catalyst. Two C-C bonds, two C=N bonds, and one C-N bond, as well as two new rings, were formed in this reaction. |
