Abstract :
Dimethyl (z)-2-[(2-methyl-5-oxo-1-cyclopentyl)oxy]-2-butenedioate has been synthesized using one-pot three component reaction between N-isocyaniminotriphenylphosphorane (Ph3PNNC), 3-methylcyclopentene-1,2-dione and dimethyl acetylenedicarboxylate. Also, optimized geometry and nuclear magnetic resonance (NMR) of the title compound are evaluated using HF and B3LYP methods and 6-311+G(d) basis set. Moreover, the 1H and 13C NMR chemical shift values of the molecule are calculated and compared with experimental results. Frontier molecular orbitals (FMOs), total density of states (DOS), electronic properties, natural charges, NMR parameters and NBO analysis for product were calculated by theoretical calculations. Finally, molecular electrostatic potential (MEP) surface is obtained for understanding the active regions of molecule.
