Visible-Light-Induced Cascade Cyclization of 1-(2-(Arylethynyl)benzoyl)indoles into Sulfonated Benazepino[1,2-a]indolones

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-
