Take your pick…︁ A practical method for the synthesis of structurally diverse rhodium vinylcarbenes from stable 1‐sulfonyl‐1,2,3‐triazole precursors has been developed. The reaction is general for a broad range of 4‐alkenyl triazoles and dienes, enabling the stereoselective synthesis of a variety of polycyclic imines, which are readily converted into amines or aldehydes in a one‐pot process.
