Photoredox-Catalysed Cyclisation of Carbyne Equivalents with Alkenes and Aldehydes to Dihydrofurans

Key Points

• The aim is to develop a new method for synthesizing dihydrofuran compounds using carbyne equivalents.
• Employ a diazomethyl-substituted hypervalent iodine reagent as a carbyne source.
• Combine the carbyne with alkenes and aldehydes in a multicomponent reaction.
• Utilize photoredox catalysis to facilitate the cyclisation process.
• Successfully synthesized dihydrofuran derivatives through the proposed method.
• Demonstrated efficient coupling of carbyne, alkenes, and aldehydes.
• Highlighted the potential benefits of using hypervalent iodine in organic synthesis.
