MeOTf-induced carboannulation of arylnitriles and aromatic alkynes for synthesis of indenones under metal-free conditions has been described. When ortho-substitutedbenzonitriles were used, indeno[1,2-c]isoquinolines were formed.
An efficient protocol for the synthesis of indenones has been developed from the annulation of benzoic esters and internal alkynes by exploiting cobalt catalyst.
通过利用钴催化剂,通过苯甲酸酯和内部炔烃的环化,已经开发出一种有效的合成茚满的方案。

A ferrocene‐initiated oxidativecyclization of benzaldehyde with alkyne was successfully developed as a novel strategy for the direct access to substituted indenones in high yields. The commercially available and cheap ferrocene was employed as an initiator.

Under redox-neutral conditions, rhodium(III)-catalyzed C–H annulation of N-tert-butyl-α-arylnitrones with internal alkynes has been realized for the synthesis of indenones under mild conditions. This reaction proceeded in moderate to high yields and with good functional group tolerance.
