Conceptual DFT-Based Computational Peptidology of Marine Natural Compounds: Discodermins A–H
A methodology based on the concepts that arise from Density Functional Theory named Conceptual Density Functional Theory (CDFT) was chosen for the calculation of some global and local reactivity descriptors of the Discodermins A–H family of marine ...

Understanding the high reactivity of carbonyl compounds towards nucleophilic carbenoid intermediates generated from carbene isocyanides [PDF]
The high reactivity of carbonyl compounds towards the carbenoid intermediate cis-IN, generated in situ by the addition of methyl isocyanide to dimethyl acetylenedicarboxylate (DMAD), has been investigated at the MPWB1K/6-311G(d,p) computational level by ...

Existence and convergence results for the Galerkin approximation of an electronic density functional [PDF]
We formulate and analyze a model for the study of finite clusters of atoms or localized defects in infinite crystals based on orbital-free density functional theory.

Abstract The molecular mechanism of the oxidation process of imine derivatives of amino acids by peracids was explored on the basis of the ωB97X-D/6-311G(d,p) (PCM) quantum chemical computations. Analysis in the framework of the conceptual density functional theory (CDFT) presents that in these lowly polar ...

Reconciling Experiment with Quantum Chemical Calculations: Electron Iso-Density Surfaces Represent Atomic and Molecular Surfaces [PDF]
The surface area of atoms and molecules plays a crucial role in shaping many physiochemical properties of materials. Despite its fundamental importance, precisely defining atomic and molecular surfaces has long been a puzzle.

A one-pot multi-component reaction was employed for the stereoselective synthesis of a novel set of dispiro-oxindolopyrrolizidines analogs incorporating a thiazolo[3,2-a]benzimidazole scaffold based on the [3 + 2] cycloaddition (32CA) reaction approach ...

Materials properties from electron density distributions: Molecular magnetism and linear optical properties [PDF]
The general goal of this thesis is correlating observable properties of organic and metal-organic materials with their ground-state electron density distribution. In a long-term view, we expect to develop empirical or semi-empirical approaches to predict

The [3 + 2] cycloaddition (32CA) reaction of an α-santonin derivative, which has an exocyclic C⁻C double bond, with p-bromophenyl nitrile oxide yielding only one spiroisoxazoline, has been studied within the molecular electron density theory ...
