Synthesis and Structure of 4-Aryl(hetaryl)-2-pyrrolidone- 3,5,5-tricarboxylic Acids Amides
Diastereohomogeneous triamides of 4-het(aryl)-2-pyrrolidone-3,5,5-tricarboxylic acids were synthesised by the ammonolysis reactions of the corresponding trimethyl 1-acetyl-4-aryl(hetaryl)-2-pyrrolidone-3,5,5-tricarboxylates. Structure of the synthesized substances was studied by means of IR, 1H NMR, 13C {1H}, 1H - 13C HMQC and 1H - 13C HMBC spectroscopy methods.
