Three-component reactions of nitroalkanes, acrylamides, and aldehydes by using a catalytic amount of KOH in DMSO gave β′-hydroxy-γ-nitro amides. Mechanistic studies suggested that the reactions proceeded by domino Michael/aldolreactions. The highly nucleophilic nature of transient amide enolates that were formed by Michael addition of nitronate anions to acrylamides in DMSO enabled the realization
