Piperidines from acid-catalysed cyclisations: Pitfalls, solutions and a new ring contraction to pyrrolidines

The success of acid-catalysed cyclisations of alka-4-enylamine derivatives to piperidines depends very much on the nature of the amine protecting group: while carbamates and related amides can usually be readily and cleanly transformed, the corresponding sulfonamides react further by ring contraction leading to pyrrolidines, especially when such substrates are sterically crowded.
