Organocatalytic Asymmetric Synthesis of Chiral Dioxazinanes and Dioxazepanes with in Situ Generated Nitrones via a Tandem Reaction Pathway Using a Cooperative Cation Binding Catalyst.

Journal of the American Chemical Society, 2016
Heterocyclic skeletons play major roles in pharmaceuticals and biological processes. Cycloaddition reactions are most suitable synthetic tools to efficiently construct chemically diverse sets of heterocycles with great structural complexity owing to the ...

Study of 1,3-Dipolar Cycloaddition Between 4-Acyl-1H-pyrrole-2,3-diones Fused at the [e]-Side with a Heterocyclic Moiety and Diphenylnitrone: A Comprehensive MEDT, Docking Approach and MD Simulation

Molecules
In this article, the 1,3-dipolar cycloaddition (1,3-DC) reactions between 4-acyl-1H-pyrrole-2,3-diones fused at the [e]-side with a heterocyclic moiety (FPDs) and diphenylnitrone are studied using Molecular Electron Density Theory (MEDT) at different ...
