Abstract The domino reactions of alkyne-tethered N-mesylhydrazones yielding fused polycyclic pyrazoles have been studied within the Molecular Electron Density Theory (MEDT). Analysis of the Gibbs free energies indicates that the more favourable reactive path is the one in which the elimination of mesylate anion takes place before the intramolecular ...

UV light irradiation enables the efficient and highly selective synthesis of spirooxindole cycloadducts through a photochemical activation of [3+2] cycloaddition (32CA) reaction between ethylene derivatives and azomethine ylides (AYs) derived from substituted isatins and secondary amino acids in 3 hrs.

The [3+2] cycloaddition (32CA) reaction between nitrone and an electronic deficient methyl acetylene carboxylate (MAC) was studied within the Molecular Electron Density Theory (MEDT) by using DFT functional combined with B3LYP and 6-31+(d,p) as a basis set.

The predictive relationship between MEDT reactivity descriptors and the actual reaction pathways was investigated for the polar Diels – Alder reactions of 1-nitrocyclopentadiene with electrondeficient and electron-rich alkenes at the ωB97XD/6-311G(d) level.
