the first total synthesis of ent-(−)-azonazine. Based on the physical evidences of synthesized diastereomer and enantiomer of azonazine, both the relative and absolute configurations of the natural product were revised. Two fluorinated azonazine derivatives were also synthesized in short convenient steps utilizing the same intermediate in this work. The established total synthesis opens a potential opportunity
