Additive-assisted regioselective 1,3-dipolar cycloaddition of azomethine ylides with benzylideneacetone [PDF]
1,3-Dipolar cycloadditions of isatins, benzylamine and benzylideneacetones were studied to prepare a series of novel spiropyrrolidine-oxindoles – 4′-acetyl-3′,5′-diarylspiro[indoline-3,2′-pyrrolidin]-2-ones and 3′-acetyl-4′,5′-diarylspiro[indoline-3,2 ...

A Molecular Electron Density Theory Study of the [3+2] Cycloaddition Reaction of an Azomethine Ylide with an Electrophilic Ethylene Linked to Triazole and Ferrocene Units [PDF]
The [3+2] cycloaddition (32CA) reaction of an azomethine ylide (AY) with an electrophilic ethylene linked to triazole and ferrocene units has been studied within the Molecular Electron Density Theory (MEDT) at the ωB97X-D/6-311G(d,p) level.

The azomethine ylide route to amine C-H functionalization: redox-versions of classic reactions and a pathway to new transformations. [PDF]
Conspectus Redox-neutral methods for the functionalization of amine α-C–H bonds are inherently efficient because they avoid external oxidants and reductants and often do not generate unwanted byproducts. However, most of the current methods for amine α-C–

Topological classification of cycloadditions occurring on-surface and in the solid-state [PDF]
The study of cycloaddition mechanisms is central to the fabrication of extended sp 2 carbon nanostructures such as graphene nanoribbons and spin chains. Reaction modeling in this context has focused mostly on putative, energetically preferred, exothermic

Fully conjugated azacorannulene dimer as large diaza[80]fullerene fragment
Heterofullerenes are an important synthetic target for organic chemists. Here, the authors demonstrate a fully conjugated azacorannulene dimer starting from a bifunctional polycyclic aromatic azomethine ylide, providing a powerful method for the bottom ...
