| Abstract: | A protocol for the three‐component 1,4‐carboamination of dienes is described. Synthetically versatile Weinreb amides were coupled with 1,3‐dienes and readily available dioxazolones as the nitrogen source using Cp*RhCl2]2‐catalyzed C?H activation to deliver the 1,4‐carboaminated products. This transformation proceeds under mild reaction conditions and affords the products with high levels of regio‐ and E‐selectivity. Mechanistic investigations suggest an intermediate RhIII–allyl species is trapped by an electrophilic amidation reagent in a redox‐neutral fashion. |
