Pd(II)/Ce(III)‐Heterobimetallic Complex‐Catalyzed Decarbonylative Alkyne Annulation Reaction: Synthesis of Spiro‐Benzofuranindenones
The decarbonylation of 3‐hydroxy‐2‐phenyl‐chromenones and subsequent annulation with disubstituted alkyne in the presence of Pd(OAc) 2 (5.0 mol%) and Ce(OAc) 3 (10.0 mol%) provided an efficient route for the synthesis of spiro‐benzofuranindenones. This reaction could be used for the synthesis of wide range of spiro‐benzofuranindenones with good yields.
