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.

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.
