Visible-light promoted cascade annulation of N-propargylamines with sodium sulfinates to access sulfonylated 9H-pyrrolo1,2-aindoles and quinolines.

Key Points

• The aim is to develop a visible-light promoted method for the cascade annulation of N-propargylamines with sodium sulfinates.
• Utilized mild reaction conditions with no transition metal or photocatalyst required.
• Employed a variety of substrates to demonstrate broad applicability of the approach.
• Successfully produced sulfonylated 9H-pyrrolo[1,2-a]indoles and quinolines.
• Showed the efficiency of using sodium sulfinates in this reaction process.
