Exploring pyridotriazoles as carbene precursors toward the synthesis of N-heterocycles. (A) Attempted carbene transfer to access fused piperazines from the reaction between aziridine 9a and Rh-bound 23a-Rh2. (B) Computed reaction profile for the process involving cis-aziridine 11a and dirhodium-bound carbene 23a-Rh2.
