Cationic Gold‐Catalyzed Intramolecular Cyclization of Substituted 1,5‐Diynes to Access Indenone Derivatives

An efficient intramolecular cyclization reaction was developed to achieve indenone derivatives. The substituted 1,5‐diyenes were converted to the corresponding indenones via a gold‐catalyzed organic transformation, and moderate to excellent yields of the title molecules were obtained via formation o...

Description
Summary:An efficient intramolecular cyclization reaction was developed to achieve indenone derivatives. The substituted 1,5‐diyenes were converted to the corresponding indenones via a gold‐catalyzed organic transformation, and moderate to excellent yields of the title molecules were obtained via formation of two C=O and one C−C bonds under mild reaction conditions in one pot. An efficient intramolecular cyclization reaction was developed to achieve indenone derivatives. The substituted 1,5‐diyenes were converted to the cooresponding indenones via a gold‐catalyzed organic transformation and moderate to excellent yields of the title molecules were obatained via formation of two C=O and one C−C bonds under mild reaction condtions in one pot.
