Under appropriate reaction conditions, a domino hydroformylation/Wittigolefination can be accomplished with derivatives of allylamines and stabilized Wittig ylides. A further highly diastereoselective aza‐Michael reaction yields β‐proline derivatives. These are, for example, useful as building blocks for alkaloid syntheses.
