A highly stereoselective route to densely functionalized cyclohexanes is described, via a Cinchona‐based bifunctional organocatalyzed Henry/Michael/retro‐Henry/Henry domino reaction. The peculiar stereoconvergent mechanism allows the creation of up to four contiguous stereocenters in a highly stereodefined manner starting from both achiral aldehydes and racemic nitro alcohols. The simple and efficient
