PEG-embedded potassium tribromide ([K+PEG]Br3 −) was found to be an efficient and recyclable catalyst for the synthesis of functionalized piperidines in high yields in a one step, three component coupling between aldehyde, amine and β-keto ester. At the end of the reaction the [K+PEG]Br3 − was readily regenerated from the reaction mixture by treating the residue containing [K+PEG]Br− with molecular bromine.

Conjugated Enynes

A stereoselective synthesis of conjugated enynes containing allyl selenide unit is reported. Selanyl-substituted conjugated enynes were obtained by the coupling reaction of ( E)-γ-selanyl vinylzirconocene with acetylenic bromide in the presence of CuCl.
