Hypodematine, a novel alkaloid, was isolated from the whole plant of a fern, Hypodematium sinense Iwatsuki. Its structure has been elucidated to have a novel skeleton of benzazocine with a phenyl substituent in 2-position. In this paper, we have finished the total synthesis of Hypodematine and its derivatives and revised its structure.The main work:1. We synthesized the hypodematine through the method of Beckmann rearrangement of benzoxyclohepten-5-one oxime mesylates that with Grignard reagents. From m-met...
