carbon synthons in organic synthesis. Recently, we discovered that furans, upon oxidation
with singlet oxygen, can be transformed into alkynes via dual C–C double-bond cleavage.
This Synpacts article presents an overview of the historical context and the development of
this furan fragmentation reaction. We also discuss its application in natural product synthesis
and a plausible reaction mechanism. 1 Introduction 2 Background of Alkyne-Forming Furan …
