Abstract :Conformational analysis of N,N'-phenylenediylbis[3-(1-aminoethyl)-6-methyl-2H-pyran-2,4(3H)-dione] were performed by using theoretical calculations. The possible stable conformers in keto-amine or imine-enol forms of N,N'-phenylenediylbis[3-(1-aminoethyl)-6-methyl-2H-pyran-2,4(3H)-dione] on its potential energy surface (PES) were investigated by semi-empirical methods and hybrid-density functional theory ( h -DFT) with the basis sets of different size and type. On account of relative energies and population analysis, the more stable forms of N,N'-phenylenediylbis[3-(1-aminoethyl)-6-methyl-2H-pyran-2,4(3H)-dione were determined.
