Abstract

We report a concise method for synthesis of dihydrofuroquinolinone alkaloids, in which the cyclopropane opening and closure was the key step. The only angluar type product was obtained in fairly high yields. IR, UV, ¹H NMR, ¹³C NMR, and MS were used to confirm the structure. A possible mechanism in also described.
