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, <sup>1</sup>H NMR, <sup>13</sup>C {<sup>1</sup>H}, <sup>1</sup>H - <sup>13</sup>C HMQC and <sup>1</sup>H - <sup>13</sup>C HMBC spectroscopy methods.
