title: Rhodium-catalyzed carbene transfer to alkynes via 2-furylcarbenes generated from enynones.
abstract: A rhodium-catalyzed carbene transfer to alkynes is reported. Easily available enynones served as the carbene source replacing diazocompounds. The overall process involved a cyclization-cyclopropenation-ring enlargement sequence.
