γ-Hydroxyl or γ-alkoxyl-substituted α,β-unsaturated carbonyls widely exist in a variety of natural products and bioactive molecules. Herein, the realization of 1,4-functionalization of 3-en-1-ynes with alcohols through zinc-catalyzed regioselective N-oxide oxidation is described. This tandem reaction allows the practical synthesis of a range of valuable γ-alkoxyl-substituted-α,β-unsaturated amides in moderate to good yields.

Key words: oxidation, 1,4-functionalization, alkynes, tandem reaction
