Exotic amino acids. 8. Synthesis of monomethyl esters of N-aryl-aminomethylenemalonic acids

Zicane,Ravina,Tetere,Rijkure,Petrova,Kalejs

, p. 840 - 845 (2007/10/03)

N-Arylaminomethyleneisopropylidenemalonates, obtained from ethoxymethyleneisopropylidenemalonate and aromatic amines, underwent methanolysis to form monomethyl esters of N-arylaminomethylenemalonic acids. The conditions of their formation and their yields depend on the nature and positions of the substituents in the aromatic ring of the initial amine.
