Synthesis of Polycyclic Spironaphthofuran Derivatives by Acid‐Catalyzed Domino Reaction of 2‐Naphthols with Tetraarylbut‐2‐yne‐1,4‐diols
Résumé
The acid‐catalyzed condensation of 2‐naphthols with tetraphenylbut‐2‐yne‐1,4‐diols affords a mixture of spiro[indene‐1,1′‐naphthofurans] and dinaphthofurans through a cascade of intramolecular reactions, whereas using the more reactive thienyltriphenylbut‐2‐yne‐1,4‐diol leads to the formation of a single spiranic compound joining a cyclopenta[ b ]thiophene to a naphtho[2,1‐ b ]furan.
