The aromatic acyclic diynes 2 and 3 have been synthesised in order to test the feasibility of a new activation towards their cyclisation. In addition, a difference of stability between 13 and 20 during the Nozaki-Kishi cyclisation reaction occurs when the aromatic ring possesses or not an intramolecular trigger device. Thus, the aromatic bicyclic enediyne 14 is stable while 21 has not been isolated.
