Four in one: A straightforward synthesis of β2,3‐amino esters is described through a new zinc‐mediated, cobalt‐catalyzed four‐component reaction between organic bromides, alkyl acrylates, amines, and aldehydes (see scheme). Synthesis involves a Mannich‐relatedconjugateaddition/aza‐aldol domino sequence, allowing the formation of three single bonds in one step. A reaction mechanism, emphasizing the crucial
