The synthesis of 5‐aryl (or alkyl) aminomethylene‐3‐(1‐amino or 1‐alkylaminoethylidene)‐2,4‐dioxo‐(3 H ,5 H )furans and 5‐arylaminomethylene‐3‐(1‐hydroxyethylidene)‐2,4‐dioxo‐(3 H ,5 H )furans (new 3‐acetyltetronic acid derivatives) are described. The stereochemistry of these compounds from the 1 H nmr data is discussed.
