Cyclization products of N-fluorophenyl-β-alanines and their properties
Vaickelioniene,Mickevicius
, p. 753 - 760 (2008/02/04)
Interaction of 2-and 4-fluorophenylamines with acrylic and itaconic acids leads to the synthesis of the corresponding N-substituted β-alanines, the cyclization of which leads to derivatives of dihydropyrimidinone, 4-carboxy-2-pyrrolidinone, and tetrahydro
