Unprotected cis‐2,3‐diarylpiperidines are synthesized through an unprecedented palladium‐catalyzed cross‐coupling reaction between aryl halides and elusive endocyclic 1‐azaallyl anions. These intermediates are generated in situ by the deprotonation of 2‐aryl‐1‐piperideines, precursors that are readily prepared in two operations from simple piperidines. An asymmetric version of this reaction with (2...
