Described is an unprecedented NHC‐catalyzed (NHC=N‐heterocycliccarbene), stereoselective ring opening of epoxy and cyclopropyl enals to deliver valuable compounds bearing multiple stereocenters. A straightforward three‐step procedure involving two catalytic enantioselective transformations has been developed and leads to a regio‐ and stereodivergent synthesis of either 1,2‐amino alcohols/diamines
