A DMAP (2-dimethylaminopyridine)-catalyzed condensation reactions for the successful direct construction of pyrimido[1,2-a]benzimidazole or imidazo[1,2-a]pyrimidine has been developed. The method utilizes readily available α-bromocinnamaldehydes with 2-am

A visible light-mediated approach for the preparation of α-bromo-α,β-unsaturated ketones and aldehydes was developed. In comparison to traditional methods that generally take two steps to afford the above compounds, this protocol was highlighted by its op

Carbenes ring true: N-Heterocyclic carbene (NHC) catalyzed reactions of α-bromo-α,β-unsaturated aldehydes/α,β- dibromoaldehydes with 1,3-dinucleophilic reagents, such as 1,3-dicarbonyl compounds, β-enamino ketones, and β-enamino esters through umpolung processes gave functionalized 3,4-dihydropyranones and 3,4-dihydropyridinones (see scheme). The availability of the starting materials, lack of external oxidant, and usefulness of the products make this strategy attractive.

A novel method for the synthesis of α-bromocinnamaldehydes from aromatic aldehydes was developed. The catalytic olefination of hydrazones of aromatic aldehydes with 2-tribromomethyl-1,3-dioxolane affords ethylene acetals of the target products in yields f
