Ring Opening of 1,1’-Sulfonyl Bis-Aziridines Derived from L-Amino Acids and DFT Study of the Affinity Toward Different Nucleophiles

Autor: Sihem Hessainia, Mohamed Dehamchia, Tahar Abbaz, Zine Regainia, Nawel Khettache

Publikováno v: Letters in Organic Chemistry. 18:977-986

We describe herein the ring-opening reaction of chiral 1,1’-sulfonyl bis-aziridines with various neutral and anionic nucleophiles including benzylamine, piperidine, acetate, allylthiolate, cyanide anion and sodium ethoxide. These reactions afforded

A computational study of the inclusion of β-cyclodextrin and nicotinic acid: DFT, DFT-D, NPA, NBO, QTAIM, and NCI-RDG studies

Autor: Houdhaifa R. Belhouchet, Tahar Abbaz, Amel Bendjedou, Abdelkrim Gouasmia, Didier Villemin

Publikováno v: Journal of Molecular Modeling. 28

Forming complexes with cyclodextrins can protect nicotinic acid (vitamin B3) from premature metabolism and enhance the solubility and stability of this drug. In this work, the formation of the inclusion complex of the neutral form of nicotinic acid a

Synthesis, Characterization and Theoretical Study of the Chemical Reactivity of New Cyclic Sulfamides Linked to Tetrathiafulvalene

Autor: Tabbi Hanane, Tahar Abbaz, Amel Bendjeddou, Didier Villemin

Publikováno v: Phosphorus, Sulfur, and Silicon and the Related Elements. 193:697-704

The synthesis of the title compounds has been carried out by condensation via a Wittig-type reaction of a pyridinium hexafluorophosphate with a phosphonate ester to give the desired (4-nitrophenyl)tetrathiafulvalene the nitro group of which was reduc

Computational study of the chemical reactivity properties of bis (trimethyl tetrathiafulvalenyl) thiophene

Autor: Abdelkrim Gouasmia, Bendjeddou Amel, Tahar Abbaz, Didier Villemin

Publikováno v: JOURNAL OF ADVANCES IN CHEMISTRY. 13:5937-5947

The chemical reactivity of four bis (trimethyltetrathiafulvalenyl) thiophene is determined by its potential (electronic) energy (hyper) surface. All the quantum chemical calculations have been carried out using DFT level of theory, B3LYP functional a
