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.

Implication

Multicomponent cyclisation constructs dihydrofurans from carbyne, alkenes, and aldehydes, suggesting a novel reaction pathway.

Abstract

Herein, we report a multicomponent cyclisation reaction that employs a diazomethyl-substituted hypervalent iodine reagent as a carbyne source in combination with simple alkenes and aldehydes. This strategy successfully constructs dihydrofuran...
