Morpholine ketene aminal is employed in iridium‐catalyzed asymmetric allylic alkylation reactions as a surrogate for amide enolates to prepare γ,δ‐unsaturated β‐substituted morpholine amides. Kinetic resolution or, alternatively, stereospecific substitution affords the corresponding products in high enantiomeric excess. The utility of the products generated by this method has been showcased by their
