Photo-induced tandem cyclization of alkynes with sodium sulfinates to access sulfonated exocyclic alkenes

Key Points

• This research aims to develop a method for constructing sulfone-containing exocyclic alkenes using visible light without traditional catalysts.
• Utilized visible light for sulfonylation and cyclization of alkynes
• Eliminated the need for transition metal catalysis and photocatalyst
• Focused on sulfonyl radical-initiated cyclization processes
• Successfully produced sulfone-containing exocyclic alkenes
• Demonstrated that the process occurs without transition metal catalysts
• First reported method for constructing these compounds using this technique
