Diastereoselective aza‐Wacker cyclization of O‐allyl hemiaminals under aerobic conditions enables efficient access to 1,2‐aminoalcohol derivatives from allylic alcohols. The scope of this method is presented and its utility is highlighted in a streamlined synthesis of the biologically important aminosugar (−)‐acosamine.
