1-(2-(Arylethynyl)benzoyl)indoles were developed as an innovative scaffold for radical cascade cyclization under visible-light and mild conditions, enabling efficient synthesis of sulfonated benazepino[1,2- a ]indolones. This method operates at room temperature and demonstrates broad substrate compatibility and scalability, with promising potential for sunlight-driven reactions.
