The Z-configurated enoltriflate 16 and ortho-ethinyl benzaldehyde were coupled giving the (trimethylsilyl)ethinyl aldehyde 17 which cyclized (-> tricyclic dienediyne 14; 21percent) in the presence of CsF, Ac2O, and 18-crown-6.A similar coupling allowed to prepare iodoalkinyl aldehyde 21.It gave the tricyclic dienediyne 13 (53percent) in a Nozaki-Hiyama reaction with stoichiometric NiCl2.
