Dearomative Indole (3 + 2) Cycloaddition Reactions

Journal of the American Chemical Society, 2014
A diastereoselective (3 + 2) dearomative annulation of 3-substituted indoles with α-haloketones has been developed. Significant regiochemical control was observed. This methodology provides easy access to highly functionalized cyclopenta- or cyclohexa-fused indoline compounds, which are common structures of many natural products.

Polymerization by [3 + 2] cycloaddition, 3. Polyimides

Die Makromolekulare Chemie, 1989
AbstractThe reaction between hexafluoroacetone azine and bis(bicyclo[2.2.1]hept‐5‐en‐2,3‐dicarboximide)s (5 and 6) (dinadimides) (mole ratio 1:1) yields polymers with number‐average molar masses between M̄n = 1700 and M̄n = 5700 depending on the reactants. The possible isomeric structures of the polymers are discussed in detail.

Organotransition metal [3+2] cycloaddition reactions

Coordination Chemistry Reviews, 2002
Abstract The review, covering the literature of roughly the last three decades, describes the [3+2] cycloaddition reactions of metalla dipolarophiles MX with organic 1,3-dipoles, and of metalla 1,3-dipoles, MXY and XMY, with organic dipolarophiles.

Diazotrifluoroethyl Radical in Photoinduced [3 + 2] Cycloadditions

Organic Letters
Herein we report a photocatalytic [3 + 2] cyclization reaction enabled by redox processes. Starting from hypervalent iodine(III) reagent and N-benzylidenealkylamines, this protocol facilitates the efficient synthesis of diverse 5-trifluoromethyl-1,2,4-triazoles, providing a direct and practical route to these heterocyclic scaffolds in moderate to ...
