A novel approach for the synthesis of morpholin-2-onederivatives from dialkyl dicyanofumarates and β-aminoalcohols is presented. The reaction takes place under mild conditions via an addition-elimination-lactonization pathway. The formation of the six- membered ring occurs selectively leading to a single diastereomer. In contrast to arylhydrazines, the reaction of hydrazine hydrate with dicyanofumarates
