The efficient palladium-catalyzed conjugate addition of terminal alkynes to α,β-unsaturated carbonyl compounds has been developed using electron-rich ligands, producing the corresponding γ,δ-alkynyl ketone and γ,δ-alkynyl esters in good yields.
利用富电子配体,已经开发出了高效的钯催化端炔对α,β-不饱和羰基化合物的共轭加成反应,产率良好地得到了相应的γ,δ-炔基酮和γ,δ-炔基酯。
