A convenient and novel oxazol-5-one addition to nitrostyrenes is reported. The reaction is catalyzed by tertiary amines and yields the corresponding adducts with total regio- and diastereoselectivity. The addition exclusively takes place at the C-2 position of oxazol-5-ones, furnishing diastereopure N,O-aminals.
