عنوان انگلیسی Theoretical Investigation on Inclusion Complex of (s)-2-Isopropyl-1-(o-nitrophenyl) Sulfonyl) Aziridine with β-Cyclodextrin
چکیده انگلیسی مقاله The present work aims to study the theoretical chemistry applied to organic systems such as host / guest inclusion complexes. In literature different molecular modeling computation methods have been used to study the complexation of the host β-cyclodextrin molecule, with the guest (S) -2-Isopropyl-1- (o-nitrophenyl) sulfonyl) aziridine molecule, as semi-empirical PM3 and DFT (Density Functional Theory) calculations in gas and aqueous phases. The present paper focus on complexation, interaction and deformation energies determination, besides geometries, electronic structure, and chemical reactivity in order to describe the changes that AZ during encapsulation in two phases and two orientations. The results obtained with the Long-range corrected hybrid functional (WB97X-D / Base 6-31G (d))clearly indicate that the formed complex is energetically preferred in both phases, and the inclusion complex in the orientation A is more favorable than in the orientation B and shows good compatibility with the experimental results. NBO and NCI analysis were performed on the β - CD / AZ complex to understand the different interactions. The 1H nuclear magnetic resonance (NMR) of the complex was studied using the Gauge-Including Atomic Orbital (GIAO).
