, (2020)
A stereodivergent approach to 2-alkynyl buta-1,3-dienes from a single stereoisomer of starting α-bromoenal has been developed. By simply switching the sequence of Sonogashira and Horner-Wadsworth-Emmons reactions, it is possible to obtain these branched d
Regioselective synthesis of α-bromo-α,β-unsaturated carbonyl compounds via photocatalytic α-bromination reactions

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
PPh3·HBr-DMSO mediated expedient synthesis of γ-substituted β,γ-unsaturated α-ketomethylthioesters and α-bromo enals: Application to the synthesis of 2-methylsulfanyl-3(2 H)-furanones

supporting information, p. 662 - 667 (2014/01/23)
An efficient chemoselective general procedure for the synthesis of γ-substituted β,γ-unsaturated α-ketomethylthioesters from α,β-unsaturated ketones has been achieved through an unprecedented PPh3·HBr-DMSO mediated oxidative bromination and Kornblum oxidation sequence. The newly developed reagent system serves admirably for the synthesis of α-bromoenals from enals. Furthermore, AuCl 3-catalyzed efficient access to 3(2H)-furanones from the above intermediates under extremely mild conditions are described. Copyright

, p. 1733 - 1736 (2007/10/03)
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
