Visible-Light-Driven Reductive (Cyclo)Dimerization of Chalcones over Heterogeneous Carbon Nitride Photocatalyst

Single-electron reduction of chalcones to the respective radical anions is a useful technique to activate these molecules toward subsequent transformations. Herein, a metal-free photocatalytic version of chalcones reduction in the presence of triethanolam

Reactivity insight into reductive coupling and aldol cyclization of chalcones by visible light photocatalysis

The reductive coupling and cyclization of chalcones to generate cyclopentanol derivatives in up to 84% yield by visible light photoredox catalysis is described. This reaction involves radical anion homocoupling, monoprotonation, and intramolecular cycliza

Aluminium chloride assisted zinc-induced reduction of some α,β-unsaturated ketones

Some α,β-unsaturated ketones are reduced to give cyclodimerization products and/or β,β-coupling products in presence of Zn-AlCl3.6H2O-moist THF and aluminium chloride acts as Lewis acid to increase the yield of the products.

Zinc-mediated reductive cyclodimerization of α,β-unsaturated aryl ketones under aqueous conditions

Zinc-mediated reductive cyclodimerization of ?,?-unsaturated aryl ketones produces 3,4-trans-diarylcyclopentanols 2 regio- and stereoselectively in good yields in a 1:4 (v/v) mixture of saturated aqueous NH4Cl and tetrahydrofuran at room temper

Cyclodimerisation of α,β-unsaturated ketones promoted by the TiCl4/Sm system

The cyclodimerisation of α,β-unsaturated ketones induced by the TiCl4/Sm system was studied, cyclopentanol derivatives are prepared in good yields under neutral and mild conditions.

Electro-organic reactions. Part 51. Reactivity and stereochemical pathways for cathodically generated radical-anions of α,β-unsaturated ketones in aqueous media

The cathodic reduction of α,β-unsaturated ketones in aqueous electrolyte gives efficient C-C coupling with the high stereoselectivity associated with similar reactions in aprotic media. The key features of these reactions are consistent with those expected from the likely mechanism involving water-templated coupling of radical-anions. As a further consequence the stereochemistry of the major products (cyclopentanols and linear hydrodimers) has been unambiguously assigned using X-ray crystallography and 2D NOESY 1H NMR experiments.

Cyclo- and hydrodimerization of α,β-unsaturated ketones promoted by samarium diiodode

Samarium(II) iodide is a strong one-electron transfer reducing agent, and is effective for the cyclo- and hydrodimerization of cyclic and non-cyclic α,β-unsaturated ketones.The title dimers can easily be prepared in good yields at room temperature under n

Reaction of Chalcone Derivatives with Aromatic Aldehydes Promoted by Ytterbium Metal

Ytterbium metal promoted reaction of chalcone with equimolar amount of benzaldehyde gave 2-benzoyl-5-phenylhydroxymethyl-1,3,4-triphenylcyclopentanol, whereas 2,5-bis(benzoyl)cyclopentanol was obtained by the reaction with excess amount of the aldehyde.In
