Furoquinolin ancaloit

Recently, some of the furoquinoline alkaloids were found to have an interesting biological activity, for example, anti-cancer, antiplatelet aggregation and antifungal activities. The interesting biological activity made these compounds 1-13 attractive targets in organic chemistry. A novel generally applicable synthesis of furoquinolines is described. The condensation of 2- methoxy aniline and malonic acid in the presence of POCl3 gave 2,4-dichloro-8- methoxyquinoline. Then, treatment of this compound with sodium methoxide in methanol under reflux afforded 4,8-dimethoxyquinoline.
