Abstract A novel and efficient copper(I)-catalyzed three-component Huisgen cycloaddition reaction of conjugated enynes, alkyl halides, and sodium azide has been developed. These reactions were performed in the absence of amide ligands at room temperature, and the corresponding mono- and bis-1,2,3-triazoles were obtained in good to excellent yields in a one-pot procedure.

A series of methyl 3-acetoxy-2-(1,3-dithiolane-2-ylidene)but-3-enoate derivatives has been synthesized by the chemo- and regioselective addition of carboxylic acids to the alkylthio-activated terminal alkynes in moderate to high yields in the absence of catalysts.
