An efficient one-pot protocol for the synthesis of functionalized thiophene and benzo[b]thiophene derivatives was developed via a sequence of propargyl–allenyl isomerization/cyclization/demethylation. As a result of the readily accessible starting materials, simple operation, and mild conditions, this reaction should have potential utility in organic synthesis.

The reaction of thioiminium salts with zinc acetylides took place at 60°C to give 3-amino-1-sulfenyl-1,4-enynes in moderate to good yields. Two molecules of acetylides were incorporated into the products. Nucleophilic attack of zinc acetylides to thioimin
